It’s a lot better than it used to be, from a Linux perspective. I switched to Mint a few months ago and it can be a bit fiddly, but I haven’t had any real issues with any of the games I’ve tried. Admittedly, that’s all through Steam, but still.
The laptop’s definitely more versatile, but there’s something to be said for the handheld form factor. If you’re on transit or something, you’re not going to want to whip out a laptop. If you’re just using it at home, though, laptop all the way.
