I've actually used the wiki built into Teams, and honestly, it's crap.

I used only the web version, and it was an extremely frustrating experience. Copy and paste seldom works as expected, with text in the page/section often permanently ending up an odd size/font. Once you have more than about 10 words in a page, performance crawls practicality to a standstill, and there are multi-second pauses very frequently. Every so often it would randomly reload the page, losing anything you'd typed recently. Also, images you insert will randomly disappear at a later date. Literally cannot understand how they could release something so fatally broken.

And it doesn't support markdown, which is a total no-go for me[0]

[0] it converts "#" to level 1 and level 2 titles, but that's it. And even that only works as expected half the time
