I'm actually in the opposite position. I've used Linux for 10 years until I recently had to switch to Mac due to work. I started off in Ubuntu in 2016 and moved to Arch in 2018. I ran it until I started in a new job.

One thing that Linux just gets right compared to macos and windows is the package managers. Brew is nice and all, but it's nothing compared to pacman/apt. I also miss it for the window managers. Coming from i3, navigating a mac felt so slow and inefficient.

Linux can be intimidating, but I'd suggest just starting off and try it. Preferably in something more beginner friendly. I've heard good things about Debian. If you want the full on "I (kinda) use arch btw", I'd also check out Manjaro which runs arch in the background.

GL!
