All other things being equal, one-handed backhand can generate more pace than a double-hander. However it is vulnerable to high bouncing balls (it's hard to generate much pace on those and they wear you out) and getting "jammed" (when you don't have enough separation between your body and the ball - it's much easier to hit with some pace using 2 hands from a jammed position).
