re: Better twist- usual suspects or sixth sense?

6th Sense gave it away too soon.

When he's shouting at his wife outside and she doesn't even notice him as she's talking to another dude.

And then of course the anniversary dinner ruined it.

So by definition, the better twist is probably Usual Suspects because it's not a slow-build but just a dramatic twist...which some people hate and think it's a cheap trick.
