With three blades you have more thrust, but a bit less efficiency. You have more spinning mass which equates to some added stability but with the weight penalty of the extra blade.

Three blades has a smoother feel, to me anyway, it's hard to describe.

You can have a totally rigid head with no damping and yet you won't get any nodding in a hover. The rigid head gives a very 'connected' feel. You can have very high agility with light blades (check out some of Nick Maxwell's flying with the three blade Raptor E700).

There are both pros and cons basically, so it's a subjective choice.
