Better as in much better framerate with no performance drops. At least that's what I've heard.

Pretty much all the games I have played allowed to disable the motion controls. I think it counts towards accessibility. Personally I really dislike the whole motion control aspect so always turn them off. Zelda included.

I'm sure there are other tradeoffs as well. But would love it see what it's like on an emulator. Or maybe not, it might make running games on the original hardware feel terrible :)
