Was George in the wrong group ?
He had the ability to lead a group of his own and certainly the songs later on . Was he "Treading Water " in The Beatles, should he have got out in 1967 and put his own band together ?
i think if anything george got lucky in meeting Lennon/McCartney, he was as said before a mediocre guitarist with mediocre song writing skills.
If you listen to most of his big songs with the Beatles it is actually the other members who make those songs, if you listen to the demo of something it is nothing special but put over it maccas great bass line and it makes it, and the same can be said for other tracks be it Clapton....
and as good as atmp was if it hadnt been for the beatles association would it have been what it was/is ?
something a friend pointed out to me is most beatles songs the vocals ,bass and drums are right forward in the mix then the guitars and keyboards are behind them, and i think he is right and i can see why because the most interesting things that went on in beatles songs came from either the vocals, bass or drums.
would the beatles have been improved with a better guitarist though? probably not because then there would have been a 3 way power struggle.
