The UU because the movies(Marvel Studio ones) require elements from the UU. The movies are a blending of elements from the two and better for it. The movies seem richer with the tied universe feel. This flows from the super-solider drive and the cameos as well.
The origins are dated and the UU are a godsend to writers scripting these movies.
I'm almost positive you already did this one.
The movies are giving us the best of both worlds and are the best overall. I say this even though I am a Fantastic Four fan and the Fantastic Four movie franchise falls short of what Iron Man, Spider-Man and X-Men fans are getting.What is better at updating and reimagining characters: the UU or Marvel Movies?
i seem to be one of not many people that really likes blue tony (ultimate iron man), but even i'll say that robert downey jr.'s tony stark is better. The only area where blue tony is better is, he has an explanation for how he survives all those falls.
