Music is very subjective, how can you have a right and wrong answer, you can't. Go to a Rush concert and see thousands digging it and try to tell me they are all wrong... you can't, it's about what way music makes you feel and that is their experience. You next poll should be "What is better, food or air?"
Me personally, I'm a Beatles nut
So much so that they poisoned two years of my life and I hardly listened to anything else. The harmonies are what I love. Rush is good too, and as someone mentioned they are very technical and that is thier thing. What does it for me is hearing two voices singing in harmony, the Lennon/McCartney harmonies were something else.
A couple of my favorite Beatles harmonies:
If I Fell (Go download this and listen right now if you want to hear how harmony is done!)
This Boy
Words of Love (Buddy Holly cover but wicked, how low can Lennon goooo...)
I Feel Fine (Just listen how great McCartney and Harrison sounds over Lennon as they go into the bridge, "I'm so glad...". Just coming up with those harmonies is amazing in itself, not even mentioning the execution!)
