head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Grand Arena
A fast neutral-heavy anime fighter where Moon Style selection and constant opponent modelling drive competitive outcomes.

Execution · Grand Arena
A 3D fighter where movement and mixup reads decide rounds.
Melty Blood: Type Lumina leans Execution (Grand Arena); Tekken 8 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
Moon Skill extensions and tight neutral movement set a high execution bar
Tekken 8
Just-frame inputs and 3D movement punish sloppy hands.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Melty Blood: Type Lumina
Moon Style matchup shifts and opponent adaptations are constant
Tekken 8
Adaptive opponents mix lows, highs, and throws.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Melty Blood: Type Lumina
No RNG; all match states are fully visible
Tekken 8
Negligible RNG in core matches.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Melty Blood: Type Lumina
Moon pairings and character-specific punish routes reward study
Tekken 8
Frame data, punishes, and movelist depth.
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.
