Ubuntu - Loved it in 2006-2012ish but I jumped ship when Amazon appeared in search. Great place to start my Linux journey at the time.
Manjaro - Only distro to ever break entirely on me. I didn’t care enough to try and figure out why.
Tried endeavor and stock arch but they weren’t my cup of tea. No real issues with them though.
Fedora - I liked for a few years but abandoned after the RHEL drama this summer. Seems to be going the way of Ubuntu. Maybe that’s just my opinion.
I use and like Solus a lot but they didn’t update anything for 2 years until this summer. I use it on my gaming PC and an old laptop for web browsing but nothing important. It’s always been solid for me, I just worry about it going extinct. They do have an updated road map and seem re-energized though. I also think it’s a good beginner distro because you don’t have to dive into terminal much, and a good distro if you are a pro, but kind of bad if you are an intermediate user because there aren’t a ton of resources on it that bigger distros have.
I mostly use Debian these days. Stable on my server. Testing on everything else. I don’t see me abandoning it anytime soon.
