I will say that AHicks is correct, based on my own experience, for exactly the reasons he stated.
With my mid drive, if I'm not geared down at the start of a big hill, there's a problem. It takes the motor longer than I'm comfortable with figuring out what the heck I've gone and done and adjust to that, so I lose significant momentum. With my hub drive, I knock up the PAS or hit the throttle and the response is instant. Same with starting from a dead stop. I better remember to gear down, or it's a slow start with the mid drive. With the hub, again, kick up the PAS or hit the throttle, and go. I like both my bikes, but the hub drive is definitely "easier" in the sense that I don't need to be thinking and anticipating like I do with my mid drive.
I've said on another occasion that if my hub drive had been available when I first purchased and IF I were confident it would have handled the hills as well as my mid drive does (actually, it probably would!) I would have probably purchased the hub instead.
