Is there any difference, pro/con, in using a powerhead vs an air stone (I'm assuming one needs a pump for the air stone too)?

I picked up a 20 gallon tank and a HOB filter for QT down the road.

Is a 50 Watt heater enough for QT, or better to just get a 100-150 Watt heater and have an extra for back up on main DT?
(Main DT is 150 gal)
