I made a similar jump over the past few years out of frustration with stagnating apple hardware (pre-m1). I spent a year with a hackintosh, which worked pretty well, but became disenchanted by the continued locking-down of the OS.

For the most part, daily driving Linux as my desktop has been great - no small thanks to Electron. Slack, Spotify, VSCode, etc. all just mostly work.

Going the arch-route took extra upfront work since you're effectively building a desktop environment from scratch, but the benefit is knowing exactly how -everything- works. If I press my "volume up" shortcut and the overlay volume bar isn't displayed, I know exactly which sway config and executable to look at. It's refreshingly simple.

The downsides are that upgrading is a bit anxiety producing (will I break anything?). HiDPI on Linux is still (in my experience) a bit of a mess. If you run wayland, you need to patch xwayland/sway/wlroots if you don't want blurry x11 apps. And there are some quirks- like, I can't drag files into Slack. Maybe it's fixable, but at some point you become satisfied with "good enough".
