I just saw Paul a few months ago, it was a great show, and to my surprise they played my favorite Beatles song, "Being For The Benefit Of Mister Kite", and "Live And Let Die", was an amazing performance. I would bet he spent more on visuals, then a lot of bands spend on their whole tour....and the sound was very good, considering it was in a sorts arena, and not a music venue.
I personally think the early Beatles wasn't very good, and I think their latter music...after they started dropping acid, basically....is much less "poppy" then the latter music they put out, so as a whole, I would tend to lean towards Wings, as my choice. I really liked George Harrison's solo music, but I was far from a fan of John Lennon, solo or otherwise...and Ringo, was just Ringo.
