More drawbacks I can think of
- VR gaming is a much worse experience due to neglected linux drivers and SteamVR linux version
- Discord screen sharing is in a bad state still
- Variable refresh rate realistically requires wayland on a multi-monitor setup which comes with its own caveats
Despite these I think if you get a setup that works for you the experience will be better on Linux.
For distros I’ve always been of the opinion that Arch-based is the best choice for people switching due to the vastness of the AUR; for that I can recommend EndeavourOS.
The quantum leap for linux gaming was that one guy who wanted to make nier automata work and developed dxvk.
