Geek Fun: Starship Smackdown at Comic Con 2010

Which science fiction starship is the best?  Let the geektastic debate begin!  Last night the Cine-Sib and I, with some friends, were busy arguing about this over dinner.  The Cine-Sib wants the Defiant on there.  I still stand by my TARDIS even though it doesn't have any weapons -- since I think you should expand the definition of starship awesomeness beyond just the ability to blow stuff up (though that is pretty cool too).
