I've been using bazzite for about 7 months I think. I use my PC for Internet and gaming stuff for the most part, not a "workstation" user.
I prefer it to relying on windows, and I find lots of cool interesting things I didn't know I'd like in kde plasma.
The built in app store, Bazzar, is really well tailored for gamers, plus lots of other utilities and such.
The "immutable" build of Bazzite (universal blue fedora) just means you'll be installing most stuff as flatpak packages "on top of" your OS like apps on a phone. If you need something that isn't built to be installed like that, you'll have to spin up a container of the distro it expects, but I did that within a week and it wasn't too hard.
I'm still running a 1080ti, so I'm not exactly peak hardware or performance chasing. Only problems with games so far are shitty DRM or Anticheats, and I don't like competitive multiplayer stuff anyway. Check protondb for your favorites.
It's stable. I don't think I've ever "crashed" or "blue screened" my OS. Did have 1 lockup where I had to turn it off manually.
Expect to make "gamer rbg ram" levels of sacrifice in a few places, as with all free/foss/not mainstream products.



Zero click hacks often find exploits in the victims OS, places where protocols run automatically. Stuff like Bluetooth device identification, wifi, sms protocols. I'm certainly no expert, but they are rare and highly coveted, and nation-states spend a lot of resources finding them. Ethical hackers also look for them, to notify the software/hardware creators and get them fixed.
