. . or tourque for all you who spell it wrong!
All other things being equal, larger diameter = more thrust and larger pitch = more speed, but, generally speaking all other things aren't equal!
As with the selection of gear ratios in a car ( a very close analogy in many respects) it all depends at what revs the torque is produced, what shape the torque curve is, how much 'torque back up' there is, what the maximum usable revs are etc etc.
