I have played BOTW for at least several hours with pratically every controller option available.
Wii U Pro Controller - Tremendous. Love this controller.
Wi U Gamepad - plays good, looks hideous.
Joy-con grip - Works perfectly fine. Very comfortable.
Switch handheld mode - Least comfortable way to play, by far.
Switch pro controller - Works great. To be honest I still like the Wii U pro controller better though.
