Best football out right now is the Nike Aerow. It's absolutely superb. Lasts long, hits incredibly.
Next best, in my opinion, is the Puma dimple ball. I don't know the name, but it's the MLS ball. It hits as well as any ball out there, but loses points to Nike by having dimples. It flies very true.
Over-r.a.t.e.d crap - AKA the Euro2004 ball. Floats, is too light, hard to get good crosses, free kicks, or long range shots off.
The Adidas Champions League ball is class. Hits very well. A little light, but an excellent ball.
Unde - r.a.t.e.d. is Select balls. You can hit a ball very well with them, durable enough, and reasonable prices.
