if for you better is the one that rev higher then the malossi is better. If for you the better is the one that allow you to mount longer gearing ratio then Polini.
Polini works well bolt on, and then gets better the more work you do.
The malossi needs everything to make sense, it means work to the case, racink crank, better special lip with reed intake and expansion exhaust.
