Fellas, there's a lot more to propeller selection than just the number of blades. Learn to read between the lines if all you can do is study marketing material.
What does a four blade propeller
usually offer? More blade area.
When does one want more blade area? When the power to boat weight ratio is low and/or the propeller size is limited by gearcase size.
