True FH has better LEO performance but NG has better GEO/GTO performance (the main difference coming from the more powerful LH2 upper stage). The difference in fuel in the NG will probably mean a higher cost for NG (amongst a host of other reasons), but the question is by how much. FH also has to fully discard all the Stage 0/1 boosters to achieve 65t LEO. SpaceX on the other hand get much better economies of scale as they launch far more frequently.
