I have the Aramith tournament, an older set of Aramith balls (I think it was "premium" or something like that which is a silly name for their mid-range balls), the Dynasphere bronze and Dynasphere platinum, and I've played with the Cyclop hyperion set. It was a waste of money to get all those balls.
Very marginal difference between any of them. So slight its probably my imagination, and not enough of a difference to be meaningful even so.
I can't tell any difference between the Dynasphere Bronze set and Platinum set at all, other than they are a different type of ugly. I also don't think they stay cleaner than other sets, which I've heard people suggest.
The Aramith tournament plays better than the midrange Aramith set. But not that much.
For what it's worth, I put the Dynaspheres away and went back to the aramith tournament.
Get whatever set you think looks best and then forget about it until they need to be replaced.
