I use Yuzu.
its pretty good, depends on the game of course.
I recently loaded Fire Emblem Engage, super mario oddosy, donkey kong tropical freeze, and both zelda BOTW and TOTK. I was running them on my steam deck so performance was so-so, some games better than others, all of them definitely playable though (except super mario sunshine, but that was one I tried probably almost a year ago, yuzu is better now)
emulation still proves to be the best way to play.
If you want to daily drive linux, I recommend just installing only linux and commit to it for a bit. If you dual boot you may just find that you end up booting into windows and dont go back.
also recommend considering a rolling release distro. idk about Ai stuff but for games, a rolling release is almost always better.
