i dunno which one to choose 
They are both amazing. But I personally have quite a few supernova and like it more.It is extremely stable, and plays fast slow,or however you want it.
thanks man 
No problem. And if you get it you will love it. And the new black and blue colorway is amazing IMO> ANd also the new ones are only 84$ which is amazing deal!!!
ive played both, and they are both amazing yoyos… still, I also have to say supernova… not knocking the genesis, but the super nova just feels better to me, or if you wanna go somewhere in between you can go for a Super G, that one is also quite amazing
