I made the mistake of installing Kubuntu 24.04 when I wiped Windows off my gaming machine. I regret it. It's not SO bad, but I don't like having Snaps shoved down my throat. Otherwise it's OK. And you still have great support online and tons of documentation.

The best alternative in my opinion would be Arch via the Endeavor OS distro. It's easier to install than standard Arch, it has an increasingly large community, awesome documentation (Arch Wiki), and is packages are up to date. And I think it's a rolling release? (Correct me if I'm getting)

Otherwise if you want stability, I'd suggest Debian stable. They just released a new stable version not too long ago so it's not too outdated. It's incredibly stable. However, over time the software isn't updated to the latest releases for stability's sake. It takes two years before they release a new version kinda like Ubuntu LTS.

Edit:

I should add that with flatpaks you don't really need the latest and greatest packages in your distro anymore. It's not really a big deal if you're not on the latest GNOME or KDE Plasma. It still works fine. Application wise you can get all the latest apps on Flathub anyway, regardless of distro or how outdated your Linux is.

If I need to reinstall, I'll be using Debian (stable). I don't want any hassle.
