Just wait for the migration from Slack to MS Teams, makes me wanna stop working all together. Also, MS recently launched their Notion clone, so all Notion users in MS shops better prepare to migrate to a much worse alternative.
I've also been using MS Loop a lot and it's pretty great actually. It's clearly still under development and missing a lot of features but leaving that aside, I don't think it's fair to dismiss it as a Notion clone. It's far simpler than Notion and for writing things like company handbooks that's a good thing, actually. Sometimes simpler is better. If you need all the tables as database stuff, then use Notion. If you need a simple and clean documentation source, well I've tried a lot of these kinds of apps over the years and Loop is shaping up to be one of the better ones IMO.
I say this grudgingly, BTW. I strongly resisted choosing MS for our business. But as a small company in Vietnam we get an amazing value proposition from MS 365 that isn't even close to matched by anything else. We pay about $3.50 per user and we get Teams, video conferencing, office apps, Loop, Visio, Whiteboard, SharePoint (ok that one is genuinely quite bad), and also a load of business automation stuff in the form of Workflows that I'm still exploring. Oh and Shift scheduling. OneNote. About a hundred other things that I forget right now.
Even still I resisted but the final straw was that automatic translation is included in Teams for free. As a bilingual team that's vital for us.
By contrast, just Notion would be $8 per user. I think Slack is $6 per user. Not a lot for a western tech company, but we genuinely can't afford that. MS 365 wins by being "just good enough" at _loads_ of things, and way cheaper than the competition.
