I don’t know what’s different between the two except for the price. Also, if I were to buy 1 of the 2, which one would you recommend? Can any of you guys help me with this? Feel free to reply. 
nova is undersized version while supernova is full/oversized.
Size.

I love my supernova. I am also crazy for large Yoyos. Since the true difference is the size, pick the size you like the best and go with it.
