I love all four of them but Paul McCartney always came out on top just because I think he was the best musician. A fantastic Bassist that really made early Beatles song full of swing and expression but then a simple pianist bringing his natural bass groove into his right hand lead. Could Drum, play guitar and I thought he had the most powerful voice out of the band, songs like Long Tall Sally, Sgt Peppers among others only he could have sang. A fantastic Ballad writer and as they were a pop band, I thought he was the best pop writer. But his love songs were exceedingly fantastic! also a great composer. He was a great all rounder and really worked the rest of them hard to get the best out of their songs.
