Chiming in on some of the bigger ones mentioned recently, totally agree with Govan, he's super talented but most of his stuff is just stitching together techniques from different styles/players. King and Hammett have absolutely fallen off, but imo they were never amazing guitarists to begin with. Jack White is one that I don't really agree with, as he's not known for his guitar skills. I'd say the thing he's most known for as a guitarist is taking unconventional sounds and making them work in the context of the song, which is definitely a cool trait that isn't very common in modern guitar playing.
And now here's my contribution... possibly the biggest sacred cow on this forum, but here goes. John Petrucci. Yes, he's a monster player, but he's basically put out the same album for the past 10 years. Im trying, but I really can't remember a single DT riff off the top of my head. Again, not knocking the guys skill at all, just not into his music. Same with Abasi, great player, boring music.
