The more I think about it, the '93 version might be my second favorite. It's the furthest removed from the original in terms of the characters, setting and story progression, and I like that it's a very different take on the same basic idea. The ending is my favorite part, it kind of comes out of nowhere and isn't at all like how previous versions ended... which is why I think it's rather neat.
Apparently Roger Ebert thought it was the best of the bunch. I definitely wouldn't go that far, but if I had to choose one of the remakes, I'd probably go with that one.
