guthrie is the pro's pro, but personally i'll go for greg howe. love his style. groovy, bouncy, fluid. his playing is personal, i can tell its him when i hear it, can't say the same w/ guthrie. though technically adept, yet his playing still has that hint of 'self-taught',quirky sound/thing/whatever. i prefer that over the too schooled sound of guthrie, not to say its bad though.
