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.

Chaotic tag fighter whose top tiers reward blistering execution and assist mastery.

Execution · Grand Arena
A 2D fighting game where execution meets relentless yomi at neutral.
Marvel vs. Capcom 2: New Age of Heroes leans Execution (Grand Arena); Street Fighter 6 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.
Marvel vs. Capcom 2: New Age of Heroes
infinite combos and assist timing demand elite hands
Street Fighter 6

Street Fighter 6 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
Street Fighter 6
Adaptive opponent baits Drive Impacts and throws.
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
Street Fighter 6
Essentially no randomness in match outcomes.
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
Street Fighter 6
Matchup charts, frame data, and combo routes.
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.
