There is no "best ball." What there is, is the best ball for your game and your clubs. And this is something you find out only by trying different balls. And then, once you find one that works, sticking with it until distance calculation, etc. becomes second nature
I've played all the top end Nikes and, while they're great performing balls, I've settled on the level 51 (or level 53, if you like a vapor trail) Volviks. Why? Because they give me consistently good, repeatable performance with the sticks I use. At 400 (450 for the vapor balls), they're excellent value for the money.
850 credit Max balls? If you have money to burn, why not?
