This actually raises an interesting question. I say it's easier to do it since there appears on the surface to be less opportunity to mess up as with touch. Sure you could make a face etc but that just seems easier to do in stealth (not seen by cops as doing so) with a finger. [1] Edit: As only one example you could in theory program a finger that wouldn't typically be used with touch id.
