I have Fedora KDE on a few mini-pc’s as well as a Framework 13 laptop, I love it. I used to use various Debian-based distros for many years before this as well.

I love Fedora’s up-to-date packages and kernel. It’s not quite a rolling release like Arch but it’s far better than the older than dirt Debian stuff. Yes, I know why Debian is the way it is, but I have discovered that I like being more current than that these days.

There is no LTS release, Fedora aims for two major releases a year. It’s pretty seamless since underlying packages and kernel are already current.

Give it a whirl, you will enjoy it :)
