While I have not used OneNote since 2022, I can say that it got the "binder" organization completely right. I loved bucketing my work into those notebooks, with tabs containing all the subdomains. Notion keeps that momentum going, with the welcomed addition of rich multimedia …
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.
StatusPage is well suited for notifications on services and products. If you need to have a passive way to notify users, internal staff, or executives on the status of SaaS services, StatusPage is a low barrier way to do this with minimal setup and maintenance. StatusPage is not well suited for scenarios in which you want info kept private. If StatusPage is updated, the subscribers to those alerts will be notified so you just want to make sure you're addressing the right audience with updates.
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.
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.
Support is very responsive although we haven't had to contact them in a time of emergency, all of our support inquiries were answered in a timely manner and usually resolved with their first response. Support responsiveness played a big role in our decision since if we need help during downtime, we can't really afford to wait.
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.
I would say StatusPage on its own is a great service. StatusPage for Hipchat can only be used with that specific chat client. But on its own StatusPage can be integrated with many tools, like Slack, email notifications, text notifications, etc. I don't know of a tool that compares with StatusPage. You could essentially host your own status site with Greed Yellow or Red statuses, but you would be missing out on the robustness of a tool that keeps historical data, uptime, and segregates services based on components.
