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.
I personally found Fedora to be rock solid, and along with Ubuntu provided the best hardware support out of the box on all my computers - though it’s been a couple of years since I used it. I did end up on Ubuntu non-LTS in the end as I now run Ubuntu LTS on my servers and find having the same systems to be beneficial (from a knowledge perspective).
