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).
I purchased a $3400 Linux laptop with excellent hardware and I've experienced the following issues:
Sound output is garbage. Webcam barely works or straight up doesn't work on some apps. The built in microphone doesn't work with common apps like Google hangouts and Zoom. All on Ubuntu (latest). Certain input ports (like USB C) don't work for certain apps even though they work fine for other Linux users and they work on my other computers.
Oh, and when I was on PopOS, the entire system froze and crashed nonstop (sometimes I would go over a day without a freeze, sometimes it would happen within 30 seconds of booting). This stopped happening for a while after I did a complete system reset, but then it started happening again. The team was completely unable to figure out the issue despite it being fairly widespread. No hardware was damaged or corrupted as they claimed must be the case.
Basically, in my experience, Linux has a ton of issues still.
Sorry to hear the laptop you chose has poor Linux support. I wouldn't buy a new system these days without first checking how well it will run Linux, even though in an ideal world that wouldn't be necessary.
Do note that the context of my comment was Asahi Linux though.
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.
