I mean, EVH is certainly a more talented' guitarist than Cobain, but in the end I'd much rather listen to Smells like Teen Spirit than Eruption. Either way, I'm not sure why influence has anything to do with "best guitarists". Cobain's talent was not really in guitar like zander said, and I really don't see what Cobain contributed to the guitar world at all. He wrote plenty of great songs, but songwriting != guitar playing.
