I was on Ubuntu for a year. No major issues, although I used the interim releases, which are supposed to be less solid than LTS. Then, a couple of months ago, I decided to switch to Fedora, just out of curiosity. Many people stated how Fedora is rock solid, Fedora is the new Ubuntu, etc. First some rpmfussion updates broke mesa, then the ostree update broke Flatpak, and recently there was a broken kernel 6.3.11 update that affected some AMD users. A few days ago, I updated my kernel to 6.3.12, and I got frequent freezes on boot. Other users are also reporting such issues. So now I boot with an older kernel. Which is not optimal. There is no LTS kernel on Fedora, the old kernel version doesn’t receive security updates. Was it always like that, or it’s an unusual bad phase.
You want an honest answer? Fedora was never that great to begin with and went down quite a bit in quality since the whole patent debacle. I had to switch distros when Mesa was constantly breaking. Also, untested kernel updates would remove HDMI audio (and despite a fix being available they waited a crazy long time to push it) among many other things
Tumbleweed is just plain better.
I always just found it to be really, really, ridiculously slow. I swear DNF might rival Windows in terms of update slowness and it seems to permeate the whole system.
