I own both games. The MMr plays fantastic. The flippers are turned up to max, and it plays snappy like a new stern. The flow of the ramps are incredible. When you get multiball and the catapult starts throwing balls to the left inlane in combination with the other balls flyin at you , is quite the magical flow that makes this game #1. Keep in mind the GB pro that I had was so cool , I sold it and went the premium route. The artwork, sounds , lights can't be beat. The shots are different than your standard fan layout. The look , toys , colors and overall feel make GB the new kid on the block with a lot to offer. MMr has that classic williams feel with brand new parts, GB has all the new bells and whistles and stands right now as a great game. Both keepers in my book.
