I have Both a mini-z and a micro, they are not the same so comparing is un thinkable. I like the mini-z can run in smaller location the rs4 mirco can`t. When I mean I talking about small I talking about Japanese size rooms. Mircos are meant for outside running. Micros are nice, but to me they are just a little smaller then the 1/10 scale cars. The mini-z is a true small size car.
