I can't speak directly on Vim since I don't use it much. I have only used it for very quick edits and am no "Vim power user" by any measure of the spectrum. Ever since switching to OS X, I've been using TextMate. As everyone has been assuming, TM seems to be slowly dying. With the upgrade to Lion I've come across many bugs and quirks with TextMate. Chocolat seems like it's going to be something fresh and inviting for users. Coming from TextMate, I think this will solve the need for a nice, new editor that will embrace new OS features and actually be supported.
