This is a forum where people seek help. Of course you're going to see problems here. Nobody posts "hey it's been several years and I've had no problems."
Of course linux is stable. It runs like 80% of servers on the Internet.
Also can confirm. Been using Arch, which most people consider requires more fiddling than other distros, for almost 10 years now and have had few issues with it. I've had to fix my Windows install more than my Linux.
Personally, I don't get the appeal of distro hopping. I think it's nice to try different concepts, but there aren't that many.
You basically have the "classic" distributions, like Debian, Suse, Fedora and their derivatives and if you want those split up into the stable and the rolling distributions (Arch, maybe Debian Sid). Then there's the source-based distributions, most notably Gentoo and derivatives. Declarative distributions, NixOS and GUIX system. And then maybe the newer breed of immutable distributions like Fedora Silverblue.
To me, the difference between an Arch system and Debian are kind of minimal. Yet I'd always prefer Arch. But why would I hop to OpenSUSE?
Granted, I always install from the terminal anyways and build my system to my needs, so I usually don't get the default experience.
I'm going to do my best to "wait" for PopOS 24.04 before I hop out again. It seemsbI finally got Endeavour right, with hybrid graphics and all. The only pain was actually how long it took to install Lubre Wolf. Ah, and that the first attempt at installing flatpaks, nothing was showing up after install until I rebooted. But now they work as expected.
