Trey Azagthoth of Morbid Angel is insane, his rhythm and lead abnilities rival most people, and he is fairly creative with the 7 string arangements. Though he is a death metal guitarist so that rules outright that he would get no mention at all.
Jeff Loomis from Nevermore has a well rounded style that has technical ability and musical appeal.
Jason Becker, becasue he got lost in the ages thanks to ALS.
John Schaffer from Iced Earth. Perhaps near the best rhythm guitarist ever. If you've never heard any Iced Earth check out these songs in particular: Dantes Inferno, Stormrider, and Traveler In Stygian.
All honorable mentions but very rarely recognized, well except for Becker for being perhaps one of the best melodic shredders ever...eh, what'y gonna do.
