kill bill. I thought the story was more 'complete.' And it had a hint of mysticism to it, which I also like. And great action.
Reservoir dogs might have been a pick, but it's just so old-school. There were too many 'dry spells' with nothing happening, it seemed. They were short, mind, but still present. Same with pulp fiction.
One interesting thing about pulp fiction, though: the wolf was a completely unnecessary character, and his role was written very carefully such that his uselessness was, in fact, complete. He did nothing while he 'helped' the two of them resolve their problem. He instructed them to do things, but they are the ones who actually did it. He gave the guy money for the blankets and such, but it was later revealed that Jules had ~30k in his pocket at the time that he willingly parted with anyway. He didn't even give them a ride back to their houses. He did nothing at all. Kind of neat.
Inglorious Basterds because, despite Quentin's work, the rest of the team pulled it off very well. Writer, costumes, stage and art directors, actors. Everything just clicked together amazingly. Kill Bill was way too slow for me.
I'd have to say pulp fiction. Just a perfect example of how f***ing excellent tarantino is. Usually I can barely sit through a movie that isn't complete action, just don't really have the attention span for it, but with pulp fiction I absolutely loved it.
