Hi, this is the exact same behaviour. The MMR is lighter and technology is totally other. It depends of your pref. Do you want to be able to repair yourself or not (MMR is impossible), if you like new glittering things or a used machine (personnally new is better). Flipper bats are managed differently, here again, it is a question of feeling. For me the quality of MMR is not the same as a WMS.
And something which is not objective: that game does not deserve the price.
Good luck in your selection.
