All balls are good - if it's the only thing you use.
That said. Love the NBL wilson balls (same ones that are used in the NCAA I believe).
The new legacy spalading TF1000s are not as good as the OG TF1000s.
Molten's seem a bit lost now. There was a time when every man and the their dog had the GF7 synthetic ball. But now Molten has all different types, I don't know which is the top shelf model.
I also bought an NBA game ball for shits and giggles, after hearing from many people they dont' like them. The word is you really need to wear them in for a while before they come good.
All balls are different I guess, the NBL Wilsons straight out of the box are the nicest to play with.
