Technically, Delta IV Heavy was the more capable vehicle... but yeah (tonnage to a given orbit). Atlas V Heavy would've been much cheaper for what it needed to do, and much less of a manufacturing nightmare than Delta IV Heavy turned out to be! Turns out the 2 side boosters of Delta IV H are unique to that design, whereas Atlas V would've used two stock CCBs with minimal modification.
