Tennis is more a battle between Nike and Addidas in my opinion. Addidas definately makes the best shoe on the market by far and then there isn't much of a difference in the style of clothing. I've found all the dry-fit, climacool, whatever technology to all work equally effective. Between Nike and Reebok I'd take Nike. Reebok is going to have a big problem with losing Roddick because they started building most of the brand around him, while Nike lost big name players, Agassi is going to be gone soon anyway and they didn't build half of their line of clothing and shoes around him anyway. I'd also point out that I think Nike has betters women clothing, and this is important when, although I end up having to wear whatever I buy, I end up looking and what the girls are wearing more than myself.
