This has long been a favorite song of mine - it's always seemed like a very honest and interesting song. Interestingly, the only one that I've ever really listened to, and what remains to be my favorite of these three versions is 311's.
311's version isn't all that different from the original by The Cure, which in and of itself is a fine song. Death Cab for Cutie's version seems a little more indie to me, but the vocals really work with these guys.
