Considering that we have no way of knowing how to compare the phaser and warp technologies of the Abramsverse and the Prime Timeline, I don't think there's any reasonable way to answer the question of whether the U.S.S. Vengeance could defeat the Enterprise-E.
Hmm.. they never hit the same targets? Didn't shoot asteroids? That's what helped me realize the strengths of Star Wars ships vs. Star Trek ships. Look for common targets in both universes and see how much damage was done. Buildings? Unshielded ships and objects? Nickel-iron asteroids are the same no matter what.
I'll have to eventually watch the Abrams movies again and look for common targets such as structures, people, etc...
