Quicksilver, according to Marvel

While Marvel didn't have the rights to any other mutants except for him and Scarlet Witch, they kept very close to the comics and actually made him an Eastern-European, with accent and all. And this Quicksilver is precisely like anybody would have imagined him: protective with his sister, very anxious (although the other version was also), helpful and selfish, and rather unaware of the full extent of his powers (all the skidding made him look as a newborn miracle, so to speak). And this is a nice addition.

So which one was better?
