Out of the ones listed I would like Williams, Shore, Newton-Howard, or Powell. Actually leaning toward Powell. Too bad I accdentally voted for Williams as I didn't notice John's name on there lol! His X3 and Bourne scores are among my all-time favorites. I wish they had mixed the audio better in X3 because I don't remember being as impressed with it in the film as I am on CD. It's fantastic.
Anyone who is the best to deliver a truly epic and heroic score befitting the character and direction/style of the film is my choice in the end, though. Whether it's one of those guys or someone I've never even heard of.
