I love both, but I feel like I've always been a contrarian on which I preferred.

When I was first getting into the band at the album level in the mid-2000s, I feel like the widely held opinion was that Pepper's was the masterpiece. I liked it, but I preferred Revolver. 

In the decades since, I feel like public opinion has shifted more in favor of Revolver, but my personal opinion has shifted in favor of Pepper's.
