Hi Big Sheesh,
First thing is do you like the oversized head or a smaller profile head?
As for products, (I'll stick to OEM) the
Taylor Made R7 (not surprizingly the most expensive) is the cream of the crop right now, and their R5 is right behind it (quite a bit more affordable).
Ping's G2 is a close as well as
Cleveland's 460 launcher and Cobra's SZ. If you are looking for a head smaller than 400cc, I would suggest the
Titleist 983K.
Taylor Made definitely dominates the driver market - both on the PGA tour and for the weekend duffer.
Instead of just buying a driver off the shelf, I would suggest testing a few drivers out. Ask at your local golf store if you can hit a few balls with each so you can determine if you like the feel/look/playablility. Make your decision from the results.
