The Vans Aircraft forums have data from propeller tests, where they tried different props on the same engine and airframe.
It's good reading, and a summary is:
Hartzell C2YR-1BF/F7496.........208.9 (metal)
Whirlwind 200RV....................206.9
Whirlwind 200c.....................205.6
Hartzell C2YK-1BF/F7666A-4..205.4 (metal)
Aeocomposites...................204.6
Whirlwind Series 150...........201.9 (3 blade)
MT MRV12B/183-59............200.7 (3 blade)
Fastest prop METAL two Bladed F7496 Hartzell
Slowest 3 Bladed MT composite/wood (by 8.2 MPH slower)
Least expensive prop Hartzell C2YK & C2YR
Most expensive Aerocomposite (I think?)
