The chorus

Sometimes this is obvious, for instance when one line is repeated over and over.

But musically, what makes a chorus a recognisably different thing from a verse? Sometimes the verse is the best part of a song, but it will still sound like a verse and not a chorus.

A stupid attempt at explanation of what I mean now. When Oasis first appeared, I thought that many of their songs were decent enough tunes until they got to the chorus. I thought their choruses were rubbish. Then I realised that, like the Beatles (of course), the songs in question didn't actually have choruses. The bits that I thought were supposed to be choruses were effectively middle eights. (An example: "Standing at the station / In need of education...", whatever song that is.) Once I understood this, the songs sounded fine. Now why would this be?

I'm looking for answers from musicians, mostly, who would be able to explain what I don't understand.
