Chose Slack
Slack was more of a company directive. Teams has its strengths. But Slack definitely seems more mature in terms of features that engineering teams love. Video conferencing is much better in teams.
Chose Slack
I think it stacks. I haven't seen those products in the last few years, but I feel like the way Slack has evolved and how much integration it has with Salesforce. I don't think any of the other tools I've seen do that.
Chose Slack
In my opinion, the closest to Slack in terms of UI is Discord. But Slack is much more professional with more functionalities that doesn't require very technical knowledge (good for our older staff who began their digital journey within the last decade). In terms of workflow …

better price and less spam with Slack. It was the best decision to switch to this communication platform for our company. We would do it again if given the opportunity.

The other platforms have valuable features (like progress kanbans and storage for big files) but none of them work on their own. Slack is the central hub that we use for all communications, discussions, and meetings.

Slack excels at versatility and ease-of-use. Everyone knows …
Chose Slack
In comparison to Teams, I think Slack is a much nicer platform to use. If your technology department allows you to integrate third party applications, it can work really well paired with zoom, sharepoint etc. I think for many mid sized businesses it can be a good fit to enhance …
Chose Slack
Slack is better suited for actual work teams rather than communities, so it wins against Discord. About HipChat - in my opinion, it was a dinosaur that is not discounted, and it's obvious why, considering the type of product Slack delivered!
Chose Slack
From a corporate standpoint, I don’t really have another example. On a personal level, the closest comparisons would be WhatsApp, Messenger, or KakaoTalk. To me, it feels like — as I said — the corporate WhatsApp. Not that Salesforce wants it to be compared that way or used …
Chose Slack
No, I use many. I use Google Meet, I use teams, I use many others. Again, it's the same, not many things, but if I'm repeating myself, it's all about sharing the information, how quickly it's effective, the quality is good, the huddle is fine, you can share all the, so all the …

Microsoft Teams feels clunky in comparison to Slack. Slack feels more versatile and intuitive, and much more tech minded then Microsoft Teams does. I would say Microsoft Teams may have the advantage if your business is fully with Microsoft (ie the full Office suite), but other …

I've dabbled with Microsoft Teams and Zoom's chat features in past roles at startups. Teams integrates well with Office but feels clunky for quick searches and daily chats. Zoom is great for video but lacks robust file sharing and app integrations. Slack wins for us with its …
Chose Slack
Teams and Slack both have Pros and Cons. We use both for communicating. Microsoft Teams is good from the prospective that you can set up Distribution Groups and Private Groups for sharing out links from One Drive and Sharepoint. The integration is built in so that all the …
Chose Slack
Slack has a more modern feel as far as ease of use.
Chose Slack
Slack holds up fairly well with the others. They all have the same basic features. Where they do differ is the execution. You can tell that for Teams and Discord, they had Slack in mind when they were designing their system. These two would be the closest to Slack, even in …
Chose Slack
The applications i have used earlier is not much user friendly, I can not do video calls in groups and tagging system is not available accross the company. Feedback and survey or process updated delivery feature makes Slack different than other companies. Slack is really time …
Chose Slack
I like Slack better than ClickUp, because I would spend 30-60 minutes a day updating my ClickUp tasks. The way ClickUp was used was very micromanaging. I billed by the hour, so I was willing to put in the time to alert the boss what tasks I was working on.

Chose Slack
Teams is better to schedule meetings with and integrates with Outlook well, but that leads to duplicate notifications for things, which is distracting and a waste of time. Messaging in Teams not great compared to Slack, and has the potential to have people outside your …
Chose Slack
Ease of use is a game-changer. Slack works so intuitively. People started collaborating automatically, and digital communities started to appear. We haven't seen that kind of engagement with other tools or workflows. It makes working together fun, and that is something that …
Chose Slack
It's just an actual messaging soft ware to use, compard to other that can be underwhelming or just not useful when your company is growing, Slack keep unity and option for communication that caters anyone, depending on what they feel comfortable and with what type or works they …

Chose Trello
I've tried using an agenda, making tasks in the Google Calendar, copy the Trello organization in Notion. But I can say confidently, that nothing beats how nicely and attractive Trello looks. It's not only visually appealing, but it's super easy to use and great to have a follow …

Our business ended up using Monday due to the holistic nature of the tool. It allows us to collaborate amongst teams and see the project as a whole easier. Trello is for personal usage and task management. I use Monday to organize my overarching needs, and then put specific …
Chose Trello
I don't feel that Trello stacks up to these other tools as well. I used to use Trello much more in the past and, over the last 5 years, have consistently used it less and less because it is easier to stay within the workflow of the tools I listed above.
Chose Trello
Okay, I have to say that at the organization where I work, we completely switched from Trello to Monday.com, and it wasn't an easy decision. As I've mentioned throughout this review, I think Trello works perfectly for small and medium-sized businesses and/or entrepreneurs …
Chose Trello
We actually use both in our company. I personally prefer Slack just because I feel like it gives me more avenues of communication with my peers and coworkers then Trello does.
However, Slack would fail to meet our business requirements for what we need to succeed with new …
Chose Trello
Ease of adaption for small startups.
Chose Trello
Trello is more visual than Todoist and MS To Do. For me, the major advantage of Trello is its functionality around creating Kanban Boards—there is not the same flexibility or options in either of the other two products. I was also able to seek advice from colleagues who were …
Chose Trello
Asana is awesome but it comes with a price. For a startup pricing hurts. ClickUp is so vast and has a lot of areas to get lost in, if you don't set some standards there are many ways to do it wrong. Slack is just a communication platform, you can collaborate and stuff but not …
Chose Trello
Trello is more simple and not as "robust" as the other tools, but it's easier to use and manage and understand and ACTUALLY get stuff done with. It's simplicity is part of the beauty of using it. You don't need a million options that nobody uses, you just need to get stuff done.
Chose Trello
We found that those software, while they included Kanban boards, offered a lot more features. Our tickets tended to get lost and it was harder to navigate through. Our Product team didn't particularly like how they functioned as much.
Chose Trello
Trello won becuase of the easy drag and drop feature that makes it simple for team members to jump on and use from day one. That said, Asans has way more features and for a tech-savvy person it would be the choice; it is still user-friendly. While it has a steeper learning …

Trello provides precise goal setting, targets, and activity tracking with minimal human intervention, while Trello provides tags and tasks to add users and communicate visual task organization. Trello also offers real-time updates, team collaboration, and project progress …
Chose Trello
Easier to use and easier to integrate with 3rd party software. Better design and we don't need to build everything from scratch.
Chose Trello
For our purposes and my role in the business, Trello is simpler and easier to use. I found Jira very hard to navigate to individual projects, and the process of creating a card was very time-consuming. That said, I think Jira performs a number of roles that Trello doesn't, and …
Chose Trello
Trello offers wide range of features even for free users which other vendors rarely offers.
Chose Trello
I have been able to use the free version of Trello for many years and for the free version, this platform offers incredible value. I have not yet found such value in other free versions of similar platforms. This platform is also very easy to use as a first time user.
Chose Trello
Trello is more in-depth and task-driven, whereas 15Five is more accountable and has personal weekly goals and accomplishments. Trello can be divided up to allow others to do the listed task, and all employees work together to accomplish and complete each required ticket/card …
Chose Trello
We are still transitioning into using Trello but used ActiveCollab in the past for our website management and projects. I do like the layout of Trello better and feel that the notifications work well.
Chose Trello
I also use Whatsapp chat as a task management tool. Whatsapp group chat is very convenient for assigning tasks and making follow-ups. Trello currently lacks here. Whatsapp chat is also way more handy and user-friendly than Trello, because of its better interface and engagement. …

Slack is ideal for Scrum and agile teams that need continuous communication during sprint planning, daily stand-ups, backlog refinement, testing, and retrospectives. Slack is well-suited for maintaining team knowledge through searchable conversations and dedicated channels, where experienced team members help onboard new QA analysts.

Trello is great for cross-team communication and intra-team organization. It's simple to get setup, with flexible tools that give businesses control over how to make Trello work the best for them. It is an amazing platform for operations tracking, project management, and even organizing customer service requests for a smaller business.

  • seamless notifications across multiple devices
  • The ability to easily tag a team member to urgently attend to a specific escalation.

  • Helps track employees "to do before hire", "to do after hired," and "to do when employee leaves"
  • Provides important information on each employee like personal information along with data collected during the time of hire and during employment time
  • Allows more than one person to be assigned to a task per employee and will remain open until everyone involved has completed their task

Cons
  • Would love a better integration with GitHub. For example, notifications when your PR is updated, when review is requested, @-mention in comments, etc.
  • Improved "Later" tab, for example the ability to create to-do lists or making the "Later" tab into a more powerful to-do list (annotate items with notes)
  • More powerful integrations, e.g. Google Calendar could render a calendar view within Slack, rather than sending the daily schedule

Slack sitll lacks in functionality. It's better than Skype for Business in many ways, but it is still another chat/message board app. It has limits in free version and paid versions. Also Windows app has errors that bother me, for example, I see number on one of my team's icons. It suggests that one of channels has unread messages; I check all channels - no unread messages, but that "1" still appears

I am very likely to renew Trello, because it doesn't cost anything to do so. I am also very likely to use Trello's upgraded features in the future because a lot of my team's data is stored on there and they have already gotten used to the platform. Trello is very easy for new team members to pick up, making the onboarding and usability very streamlined.

Usability
My rating was 7. Its intuitive interface and user-friendly features like channels, threads, and integrations make it excellent for team communication and onboarding. However, its usability is held back by the resource-intensive desktop app and cluttered feeling in large workspaces. The mobile app's performance and unreliable notifications have also been noted as weaknesses.

I am technology illiterate, it's my Achilles heel and this program is so easy to use. I have been utilizing it for a decade now. It makes organizing and prioritizing my life, my work, my business, my kids life, etc so much more manageable and without having to hold on to a bunch of into in my head. I can find it and locate it quickly and easily in Trello.

Performance
Slack is a soft app, we don't have many issues with it. I recall one or two people complaining about something during our usage period, but I didn't have a bad experience. When the app is slow, usually the problem is with my computer or my internet. The app works just fine.

Support Rating
Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.

I haven't had much need to contact their support because the product is easy to use and pretty bug-free. I did reach out to them about swimlanes and I was able to find the information I needed very quickly and it was thorough and accurate information about current functionality. I love that they use their own product. That's always a good sign.

For our small business, getting a few of us started well on Trello was the key, I think. As long as a couple of us were really comfortable with the interface, we could lead others and help them with any questions. From now on, anyone who works with us just naturally uses Trello for information sharing - it's just part of what we do.

Teams and Slack both have Pros and Cons. We use both for communicating. Microsoft Teams is good from the prospective that you can set up Distribution Groups and Private Groups for sharing out links from One Drive and Sharepoint. The integration is built in so that all the Microsoft apps run natively with each other. Slack benefits from organizing different topics in channels that are all under one overarching project. These channels are easily created or destroyed depending on the coding issue at hand.

  • It's been an essential tool for our onboarding team. We wouldn't be able to operate without it.
  • It's been a very affordable investment for our team as well since we still use the free version.
  • We have had a negative return in the fact that there aren't any reporting tools within the app. We have to spend time tracking certain elements manually.
