Heh, I hope you know I wasn't all that serious with that. ;)
About them, well, to me TftD is better for numerous reasons, including underwater setting. :) I think that the more detailed and much bigger maps, much lesser clips for guns and overally higher difficulty appealed to me more than the first game. But of course this is just an opinion. :)
For what it's worth, I also had great fun with X-COM: Apocalypse, even though I've learnt that most people were disappointed and that there were a lot of cuts on there. Still I think it was a very good game.
