Beatles are way more influential on music, but Pink Floyd was the better band. Deeper, more boundary pushing music. But without some of the Beatles’ later stuff Pink Floyd wouldn’t existed as we know them. The first half of the Beatles’ catalog is pretty superficial, though there are some good songs there.
The Beatles sold twice as many albums as Pink Floyd. However, The Wall and Dark Side of the Moon sold more than 1(compilation album), sgt peppers lonely hearts club band and abbey road. The Beatles followed the civil rights movement, the Vietnam war, protests and the first band to openly mention their use of LSD. Pink Floyd sang about greed, conformity, making a mark in the world and personal identity.
