Escape from Hoth, as it's an objective map and space map. I also like the TIE Fighter feeling I get from it, and the look of several TIEs leaving the hangar bay at the same time. The only thing irritating me is the newcomers (who are still welcome to play the game, of course) who don't know how to play it yet.
