Plasma has a cycle of releasing a bunch of new features and changes, and then squashing bugs every week when they discover them.

Debian is on a 2+ year release schedule, and the packages are frozen long before the release. So plasma might be either working fine, or be broken for 2+ years.

Fedora is semi-stable because it's on a 4 month schedule, and AFAIK they don't rush upgrading to new major plasma versions, so plasma works a lot better.

Generally from my experience, plasma works best on rolling distros, while it's crap on stable ones. Stable DEs like xfce are incomparably better suited to stable distros.

I haven't had plasma crash on debian, fedora, or opensuse using wayland on three completely different, albeit older setups. It was completely unusable briefly on opensuse with an Nvidia card, but zero crashes that I can recall.

Same, went to Bazzite after a decade on Fedora, it's been YEARS since I've had any issue with Plasma

I've been using Plasma Wayland on Bookworm since Bookworm came out. Never had any issues. I'm using AMD GPU though.

I've used it on Bookworm for like a month, then gave up and switched to X11.

Nope, plasma-session crash means all your windows are goooone.

If it's only plasma-desktop or kwin crash, you can generally restart it from a terminal, and you need one terminal window open at all times to do that, since you won't be able to launch a new window with no desktop, or you try to launch it from the text console, which works badly because it won't see your plasma-session environment.
