For a system that has so many games with stylized art directions, this is a tough one to call.
So for that reason, I am going to go with a nomination that is outside the box, and say Warframe. It has a more realistic style and looks great on Switch. It runs smooth most of the time and maintained parity with all other versions when it comes to gameplay and features. The only downfall is that it runs at 30 fps instead of 60, but it works for this game and I have had a blast playing it.
