Kurt Cobain didnt even reall do anything but snort a lot of coke. Hendrix wasnt the best guitarist of all time, in my eyes he was second S.R.V. was the best guitarist of all time. Hendrix was more revolutionary because he actually started something, Cobain was just following what the Ramones and The Sex Pistols had already created, but 1990's style pissed off grunge. I also think that Hendrix was more innovative than a revolutionist, he never really called out of any revolts or anything. Now RATM that was a band going for a revolution... :)
