Timmons is good, but i dont know if he is quite up there with those guys though. It is basically to hard to say anyone of these guys are better than another. My favorite is Satch though, and my least favorite is Gilbert, because his shred gets a little old. But some may say yngwie's shred does too, which i would disagree, Yngwie plays alot of Classical Nylon acoustic, and makes alot of guests appearances on cd's, in whcih he plays with lots of feel. ( Such as Plant X).

It is just too hard to tell.
