False dichotomy.
The Beatles were world class musicians. Isn't One Direction some bubble gum boy band?
Boy, that's a hard one ! Beatles all the way ! Let's see One Direction stay on the charts as long as the Beatles. Not going to happen !
What? Are you kidding me? The legendary Beatles vs the flash in the pan One Direction? No contest. Who will even remember 1D in 20 years?
The Beatles, obviously.
The Beatles. They're classic, like Queen and Michael Jackson, you don't get artists like them any more.
Both
The Beatles, forever and ever.
