Elder scrolls wins, but only because I've played Skyrim and now the last two Fallout games feel a bit underdeveloped; a lot of the features I saw in Skyrim made me imagine analogues that would appeal to me in a Fallout game. Fallout's combat system, though fun, is a bit crude I think. Not to say its bad, heck 3 and New Vegas are two of my favourite games, its just I prefer the Elder scrolls series more.
