While that’s an easy answer for some folks, I happen to really like both bands. No single Beatle had the stage presence of Mick Jagger, and to this day it’s hard to beat a Lennon and McCartney song. Both bands produced great albums that stand the test of time, and their considerable impacts on music and popular culture are undeniable.
You know what? I use them all depending on what I’m trying to accomplish. They each do something “better” than the other, and ultimately, my usage is based on need rather than brand loyalty.
