Stones vs Beatles

I have listened to both these groups growing up my father is a huge Beatles fan. I am surprised my dad likes The Beatles over The Rolling Stones. As we said the beatles sound was monotone and the same every song, where as the Stones had much more variety in thier music. My dad claims the Stones did more of the hard rock songs, and the Beatles played a pop, pleasant sound such as "I wanna hold your hand." Also he says he liked John Lennon and Paul Mcartney and they had amazing composing skills. George Martin pushed the Beatles to look and sing a certain way, and to have a certain style that he believed America wanted. The Beatles gain alot of credit for being the first band to change over and make it big, but the Stones influenced many artists in the future.
