Default Which blade prop do you like better,4 blade propeller or 3 blade propeller?

I heard a four blade prop will pull better at low speeds but it will have more drag and be marginally less efficient at higher speeds, is that ture ??
Some people say 3 blade propeller is enough and it also can improve acceleration and top speed.

I would like to hear your opinions as I don't know which one to replace the old damaged prop.

Well, a lot depends on the boat. The fastest R/C boats in the world run 2- and 3-blade props. Displacement hulls may prefer 3- or 4-bladed props. Throw us a bone and tell us about your boat, setup and speed requirements.

I have to agree with RPM.
A four bladed prop is generally a power prop, more for pushing or towing.
A three bladed prop can be used for either speed or power, depending on the blade shape. If it has racing blades, it normally will accelerate a bit faster but have lower top speed than a two bladed prop and, if used in a surface drive, will be faster through the corners
A two bladed prop is normally a speed prop
