It's surprisingly boring tbh. Most things, including all the gamepad stuff, work as expected out of the box. It's quite performant and could easily replace a desktop with the dock, but for portability a laptop makes more sense. I'll keep using Steam OS on it, because I don't have a use case for arch on it atm.

been keeping an eye out for a laptop with as good of a price point and performance but everything is so expensive. may get a steam deck + dock while it's on sale.
