(with a powerful enough pc) you can run games at higher resolutions and much more stable framerates on an emulator compared to the original hardware. Breath of the Wild is a sight to behold running at 4k, or even native 1080.
I was actually under the impression that BOTW ran at 60fps when docked, but I probably got my wires crossed and I'm thinking of resolution.
This is mostly in jest though, the convenience of just using the switch wherever I want rather than futzing around with emulators still mostly trumps wanting it to look prettier.
