Can someone explain the differences between these racquets?

I own the Wilson K.Blade 98, which I demoed. I thought it was great, but I want to change it now. I have only been using it since March, but I feel I need a change. I want a racquet with power more than control. I want a racquet that has good deep shots, that still go in. I need a racquet that has great baseline shots. Here are my choices from what I read and I need help choosing (price is not an issue):

Well,if you are looking for a racquet that will give you alot of power and give you nice deep shots,then your best bet would be to try the Babolat Pure Drive Roddick Plus and the Head Microgel Prestige Pro. Both of these racquets are pretty solid and are known for stability in hitting nice groundstrokes on the court. The Pure Drive will probably give you more spin, while the Prestige will allow for more flat shots. You should relaly try demoing the racquets to see which ones really suit your game.
