I think you need to stop confusing popularity, sold out concerts and record sales with influence.
I'd say there were plenty more infleucnial.
Black Sabbath is the best example, every metal band of every sub genre owes it to them in some way, then you forget about King Crimson and how many prog banRAB they paved the way for, or The Stooges and how they were a big influence on punk rock...I'd also say John Lennon, Bob Marley, The Who, Stevie Wonder, Parliament/Funkadelic, Pink Floyd, Frank Zappa, David Bowie, New York Dolls, Yes, The Ramones, Deep Purple, AC/DC, Aerosmith, Queen, The Doors, Can, Velvet Underground, The Sex Pistols and countless others are more influencial.
