+TONYPARAMOTOR Experienced pilots will notice subtle differences, but it is not really night and day. Climb rate may change some, but the biggest difference is usually in the speed at which you can spin up the prop. For several reasons, 3-blade props often have slightly less delay when throttle is applied. Obviously many variable affect the flight characteristics, and different flight characteristics can be achieved with 2 and 3 blade props. TL;DR: There are differences, but they are not game changers.
