Rockstar or Genesis

Hey guys, I just want to ask if the Rockstar is more sluggish than the Genesis ???
Because I’m having a hard time deciding which one is better, because I’ve heard that they’re both stable, the Genesis is floaty and the Rockstar as solid as a rock on the string.
And I also want to know if the Rockstar plays as fast as the Protostar/Northstar.

Thanks

well from what I see it is better if you buy a rockstar because the weight of rockstar is 1 gram less then a north star so I think it can be fast and it is solid. the Genesis is more floaty it is 3 gram les then the rockstar. either way that is two good yoyos
