Bigger flies much better because cubed loading and Reynolds numbers are working in your favor instead of against you, but keep in mind, lighter wing loadings are key if you desire slow power off landings.

So far, no one has mentioned the drag difference between larger and smaller airplanes. Often, it is necessary to keep power on during landings just to overcome the high drag produced by some airframes and low pitch, high diameter props at idle. Large biplanes and airframes such a YAK or Sukhoi with a large, round cowl often require quite a bit of power on landing just to keep them moving. One can easily end up well short of the runway if power is cut too soon. Now this can also be your friend and the braking effect is also good as it produces a more constant speed airplane during some maneuvers. Also good on landing if you know it exists and you use this to your advantage. Practice dead stick landings though so when you have to do one for real one day, there won't be any surprises.
