I suppose this is where the high ISP that hydrolox stages such as Centaur have tend to get an upper hand huh?
Yeah, although quite a bit of performance was bleed off to recover the boosters/1st stage. In expendable mode FH can lift 9400 kg to the same orbit, beating the DIV-H (8150 kg), but when they land the 1st stage cores it barely lifts more than the Atlas V 531.

Any idea on how much a Atlas V 531 costs? I'm not entirely sure how up to date ULA's Rocketbuilder is (Not that it matters though, since FH's bread and butter will be GTO comm sats).

can they strap a cryo 3rd stage on the FH? The extra 50s or more of Isp for the stuff after LEO or GTO makes a big difference.
