I think 10000ft is good for bare minimum project monitoring, we used it a large company because we didn't need to have exact numbers - it was just a rough idea to see where freelance resources were over burning. If, however you work a much smaller company and really need to know detailed information it's not as effective, there are many other software options that really allow for much closer and precise tracking. I would recommend 10000ft for companies that just need to monitor large freelance teams, track hours and higher level projects that are also monitored on other project management tools. It's a tool I would only use in conjunction with something else.
If you want a customizable solution that can be adapted for just about any scenario, I recommend using Notion. If you need a solution that's easy to share with people outside your organization, Notion is great and allows individual or team permission-setting. If you want a turnkey solution, Notion might not be the best since it requires a fair bit of set-up. There are templates that can be purchased to handle this, but I haven't found them very helpful.
I use Notion on my personal tablet, and unlike on the computer, I have a lot of difficulty editing backgrounds, GIFs, and page dividers. It's not as user-friendly, and often the elements end up cut off or misaligned, which is frustrating.
While the current calendar feature is helpful, I'd love to see more customization options. The Google Calendar style isn't always ideal, especially for tasks without specific times or for ongoing projects that require daily maintenance.
It would be fantastic to have more flexibility in customizing Notion pages. For example, I'd love to create planners with the freedom to add illustration boxes, stickers, or GIFs without being restricted to a fixed layout.
I think there's limited uses for the tool and much more comprehensive options out there for multiple tools in one. With more people working remotely, it's hard to just use email and face to face, in some ways you need to have a tool that's a fall back and a record of where you are + where you're going
Very easy to use (I learned how to use everything on my own) and I was able to set up an entire ecosystem without any courses or other tools. I often say that Notion is like Lego for adults, because there we can use all the available tools to create a multitude of things, from funnels to projects with calculated deadlines and tags.
They have been super responsive every time we need them. We built ourselves some integrations with other internal systems, and whenever we needed clarification or help to complete said integrations, they were super responsive. They have a very technical background which makes it super easy to work with when you present to them technical challenges regarding integrations or the use of their API.
The company uses both Notion and Trello within the company. Notion is more for North America employees while Trello is used between Operation team overseas and in North America. Sometimes it's a preference of how the tools look like for project management. I would say both Notion and Trello are nice tools and serves our needs.
