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

Execution · Grand Arena
A Stone-powered tag fighter where Infinity Stone selection and team synergy drive the competitive meta.

Execution · Grand Arena
A technically rich tag fighter where assist-driven combos and team synergy optimisation reward deep practice.
Marvel vs. Capcom: Infinite leans Execution (Grand Arena); Skullgirls leans Execution (Grand Arena).
Skullgirls leans a little harder on execution, though the gap is small.
Marvel vs. Capcom: Infinite
Infinity Stone tag combos require practiced execution
Skullgirls
Long Blockbuster extensions and precise assist calls demand high motor skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel vs. Capcom: Infinite
Stone selection counter-picks and team tendency reads against humans
Skullgirls
Team composition reads and opponent tendency tracking 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: Infinite
No RNG; all information is visible
Skullgirls
No RNG; all information is transparent
Skullgirls leans a little harder on optimization, though the gap is small.
Marvel vs. Capcom: Infinite
Stone pairing meta and team routing reward structured study
Skullgirls
Ratio team building and combo routing are extensively optimised by the community
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.
