Honestly I can only think of 3 or 4 fps games with expansions so it isn't that much of a choice. I probably would say RTNP though, I feel it really added to the original game and made it so much better. The second best would be Armagon for similar reasons. Both had better enviroment, features, and unique enemies. Didn't both introduce 3 enemies (Armagon's was a boss, but still)? And then there were 3 new guns... this is weird, but suddenly I see a powerful comparison between those two O_O.
