I've been using PopOS for a few months now, and I'm interested in Arch, but I'm worried about whether or not I have enough experience to do that successfully. Also, I have an Nvidia GPU until I start a new build in the next year or so. I don't know if that'll be a problem in Arch. It was a major issue with Fedora for me.
I'm willing to learn the terminal, but right now I'm still pretty dependent on tutorials to do more than basic things, like installing software. Most of those are catered to Ubuntu-based distros, so I'm concerned I won't have the luxury of guides to more complex terminal stuff.
Am I overthinking this? Or should I wait longer (maybe even until I build a new PC)?
How difficult is the transition from Ubuntu-based to Arch?
Arch has gotten much easier to install over the last couple of years, especially with the new "archinstall" tool. The hard part now is setting everything up after installation (e.g., desktop environment, drivers, applications, etc.) but if you invest a little time into learning how to read the wiki, you should be able to get up and running within 2–3 hours.
