This has nothing to do with how they preform, but I do like the way they look. I have run a 3 blade on a ST 45 for years never really noticed any loss of performance. I have had to go to 3 and 4 blade props or make landing gear so tall it looks like a clown car bouncing down the runway. With how over powered our planes really are, if they do loose anything, not sure we would even notice it.
