John Williams, no contest

John Williams' theme probably, because it is linked more than any other theme with the character.
My favorite is Zimmer's "An Ideal of Hope"
But everything in this list (except Smallvile) give this joy and vibe a Superman theme should have!

Zimmer's MoS theme for me wasn't a theme - it was just a soundtrack song, not the awe inspiring tune of WIlliams' score. Whenever anyone hears that music you know who it is, and if you're a fan, you can't but smile a little inside & out and sing along with "duh duhduh duduuuuh duh duh duuuuuuh...."

@wishiwassuperman: Yup. It's not even my favorite out of the MoS soundtrack. That would be Arcade

MoS! in before someone votes Smallville.

@smart_dork_dude: I brought the entire movie score. Krypton's Last, Arcade, I will find him and What are you going to do when you're not saving the world are brilliant.

The John Williams score is iconic and no one will ever dispute that but it's not my favourite.

The Superman: Doomsday theme from Robert J. Kral is absolutely brilliant. Sends shivers down my spine everytime.

John Williams, the all-time greatest composer of film scores. Hans Zimmer doesn't hold a candle to Williams.
