Likelihood to Recommend

Slack

When there's a team that spans time zones and continents, Slack is the perfect tool for communication & collaboration. It houses a workplace directory, so any employee can be searched for by name. Sending a direct message to any individual in the company is as simple as finding their name, then typing a message & hitting send! Essentially, it's a hub for all communication -- individual, team, and company-wide announcements can be quickly & easily disseminated using Slack.

Zoom

If you have to video conference anyone, and I do mean ANYone, Zoom is the perfect platform for that. Part of my job is helping our company adopt new technologies that we purchase, and Zoom is our preferred method. Maybe for an intimate setting or a performance review, I wouldn't use Zoom? But for almost any other scenario, I would recommend using Zoom.

Pros

Slack

  • Slack is a solid chat tool that works across a variety of platforms, with a very low barrier for entry: new users can be invited via email, and can use web-based, desktop, or mobile versions of the application.
  • Slack has really captured the zeitgeist of digital culture, including strong support for customizing look and feel (including custom emojis), and a plethora of integrations with popular web-based tools, including Pivotal Tracker and GitHub on the productive side, and Giphy.com on the fun side.
  • Slack continues to refine and improve their product, with new features being rolled out just about every month.
  • Slack offers a great value in their free version of the app, with most of the tool's functionality available for no cost.

Zoom

  • It just works. Biggest complaint with our previous solution is that it took 10 minutes to connect to a meeting. Now, our users connect instantaneously.
  • Dashboard is fantasitic. Can access real time information to troubleshoot calls.
  • Admin ports offers quite a bit of information. Like that it's a one stop shop to access everything I need to administer the site, users, run reports and access the dashboard.
  • Tickets get resolved quickly.
  • Feature requests are realized quickly.

Cons

Slack

  • The sorting of channels - it's a bit confusing, could be better sorted, it would make it easier to search and make it more agile.
  • Search - It could also improve, it is not bad, but in some cases (rare) it is difficult to find the term that you want.
  • Heavy performance in other operating systems - At least in Linux, Slack seems to do a little more machine performance than when it is used on a computer running Windows.

  • When I used Zoom while conducting some administration tasks, it wasn't quick to switch back and forth between the one providing support and the user for the copy/paste function. When I spoke to the one providing support they said it happened all the time.

Likelihood to Renew

Slack

Slack 9.6
Based on 11 answers
We've been thoroughly impressed and hence will renew the application for sure as it's meeting and at times exceeding our exceptions in getting things done. A surely shot application that is recommended for a startup, a small company and also very large enterprise and also for multiple open source projects.
Given the points stated, it's a renew for us.

We're sticking with Zoom for the foreseeable future--given its compelling feature set, ease of use, and advanced technology, there's just no other competition to be excited about. Plus it's a Gartner-recognized industry leader, so it's a rather easy choice.

Usability

Slack

Slack 9.2
Based on 22 answers
Everything just works. I think the navigation and usability is quite intuitive. I have never had to look up any information or google how to use a feature of Slack (both in the desktop form and on the mobile app). I've never heard any complaints from our other employees either. I have been asked to remind people how to set up reminders, ironically. Although that itself is really simple too (you type "/remind" and then the reminder details).

Everything is easy to understand and use, new users need no training. On the flipside there are minor annoyances such as calendar export being cumbersome (need re-auth every time) and also not having recordings shared within a team or forcing people to name them.

There have been less than a handful of outages during our two years with Zoom, and whenever there was one, an email informing us of the outage went out immediately, and they had the issue resolved shortly thereafter.

Zoom has among the best performance of any video conference platform, as I've mentioned several times. Besides that, their Chat platform works great, and their back end always runs smooth. It's unfortunate that reporting can now only be done by one month at a time, but nonetheless, it only takes a second to run any kind of Zoom report, whether it's an attendee report, Poll results, a user report, a list of meetings from the past month, etc.

I don't need to be very technical to use the Slack or to integrate tools into Slack. Adding an app (integration) is seamless and the platform walks me through the process. I can communicate with my colleagues quickly either with chat or by using the call feature to phone them. If I ever have a product question, I can quickly go to one of our product channels and search for related questions or pose a question that our experts monitor. These features have made me more effective in my day and in managing my customer base

As I've written before, Zoom makes us feel like we matter and that we're a client rather than a customer. They want us to succeed and they put in the time to make sure that we do. I feel like they're more of a business partner rather than simply a vendor or supplier. They spent a lot of time onboarding with us, giving us demos, helping us get set up, and then giving us follow-up to be sure it's going well.

If you receive any pushback from higher ups, point to any of the various positive reviews like this one. Or show Zoom's excellent Gartner report, or articles describing Zoom's partnership with Sequoia capital. It's not difficult to show how Zoom is a trustworthy industry leader with best-in-class technology.

Alternatives Considered

Slack

Atlassian actually ended up shutting down HipChat and partnering with Slack, but these are areas in which I think Slack outperformed HipChat:
  • Better UX
  • Ability to edit messages once they've been sent
  • More functionalities and integrations with different tools
  • Ability to share channels with other organizations
  • Better mobile app
  • Dark mode
Raúl Galera Domínguez | TrustRadius Reviewer

Zoom

Zoom is more user-friendly than any of these other options. The UI is better looking and easier to understand. Zoom also integrates well with our chosen hardware including Avocor touch screens, Huddly cameras and Shure microphones.

Because the Basic licenses are completely free, and because it's very easy to configure and install Zoom, and because anyone can join Zoom from a link without needing an account, scaling is a Breeze. There are absolutely no roadblocks. My company keeps adding more Zoom Pro license every week since it's so in demand. We were able to convert users from several different platforms onto Zoom with no trouble at all.

Return on Investment

Slack

  • I believe this has increased productivity amongst the team in that we can get immediate responses to issues and questions, allowing us to have a better continuous flow of work
  • Having an easy to use tool like this speeds up on boarding, as new team members can easily learn. They also will have access to all existing resources within the tool
  • We have been able to customize communication groups to include those appropriate, eliminating unnecessary noise regarding areas not relevant to particular team members.
Amy Sternin | TrustRadius Reviewer

Zoom

  • Allowed for us to start meetings at a faster speed especially with its Slack integration.
  • Integration with HubSpot has made it easy to also set up Zoom webinars and sync any contact data within the CRM.
  • Need battery chargers for laptops in a meeting lasting over an hour - drains them fairly quickly.
