Basically, I have a laptop (5800H/RTX3050) and Windows is irritating me to no end. I am thinking of completely formatting it and replacing it with whatever distro can give me the best gaming compatibility. For reference, I play - CS:GO, DoTA, Asphalt, and a little bit of Overwatch.
I was thinking of Arch since SteamOS is based on it but would like your opinion on it.
Ubuntu LTS
What SteamOS uses is largely irrelevant to the end user as Valve likely uses it as a base to build and test the versions of SteamOS that make it out. Kinda like using AOSP because Samsung uses AOSP to build their Android OS. Same but different.
Ubuntu LTS would have older versions of drivers, steam, etc
Anyway snaps would most likely bring a performance hit
