head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Grand Arena
A fast neutral-heavy anime fighter where Moon Style selection and constant opponent modelling drive competitive outcomes.
Marvel vs. Capcom 2: New Age of Heroes leans Execution (Grand Arena); Melty Blood: Type Lumina leans Execution (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

Melty Blood: Type Lumina leans a little harder on reads, though the gap is small.
Marvel vs. Capcom 2: New Age of Heroes
humans bait assists and mix high-low constantly
Melty Blood: Type Lumina
Moon Style matchup shifts and opponent adaptations are constant
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel vs. Capcom 2: New Age of Heroes
fully deterministic engine
Melty Blood: Type Lumina
No RNG; all match states are fully visible
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel vs. Capcom 2: New Age of Heroes
team order, assist synergy, and matchup knowledge
Melty Blood: Type Lumina
Moon pairings and character-specific punish routes reward study
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
