I made the same jump about 4 months ago. I had a long history of running servers and trying Linux desktop here and there and finding it lacking. I installed Ubuntu because that was the popular distro for the past 15-20 years. I gave it a month. It blew. Bugs and general broken shit that I had to constantly repair. I finally gave up and figured if I was going to spend time tinkering with every goddamn thing, I may as well be using Arch. Installed Arch and I’m having a much better time. I still have to troubleshoot and fix the odd broken thing, especially after package updates, but it’s less tinkering than I’ve had to do with either Windows or Ubuntu. I’m not saying Arch is your answer, but I bet it’s “not Ubuntu”.
