Ahem! I don't judge them the same for one. I'm judging 500 in comparison to other romantic comedies, while I'm judging Casino in comparison to other dramas. 500 is head and shoulders above any romantic comedy i've ever seen besides Eternal Sunshine of the Spotless Mind, whereas Casino (even though I like it more) doesn't hold up well against Goodfellas. Also, I gave it a 4.5 because in reality I think its like a 4.3.
