IIRC, there bunch of random things that still don't work -- no USB-C output, webcam, audio and if I've to guess suspend/resume is probably not rock solid either. The only benefit is that you get to use Linux, but then you may lose on actually getting work done without worrying about these issues. The new UI is inferior, but can still get things done.

This information is very dated. Webcam/audio work fine nowadays, and suspend/resume have never had issues that I recall. IME the feature support page is very accurate (no hidden gotchas like "technically it works but it breaks after sleep").

USB-C output is indeed not working but actively making progress (so actively that some of the related patches have been sent to the kernel mailing list and merged this very week).

Webcam and audio both work now. I can't speak to how solid suspend/resume is because I haven't actually used it--I just follow the project--but I wouldn't necessarily assume it's flaky.
