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 technically rich tag fighter where assist-driven combos and team synergy optimisation reward deep practice.

Execution · Grand Arena
A tag-team 3D fighter layering team optimization onto Tekken's execution and reads core.
Skullgirls leans Execution (Grand Arena); Tekken Tag Tournament leans Execution (Grand Arena).
Skullgirls leans a little harder on execution, though the gap is small.
Skullgirls
Long Blockbuster extensions and precise assist calls demand high motor skill
Tekken Tag Tournament
Tag combos and netsu juggles demand precise inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Skullgirls
Team composition reads and opponent tendency tracking are constant
Tekken Tag Tournament
Tag timing adds another layer of human mind-games
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Skullgirls
No RNG; all information is transparent
Tekken Tag Tournament
Open information; nothing hidden between rounds
Skullgirls leans a little harder on optimization, though the gap is small.
Skullgirls
Ratio team building and combo routing are extensively optimised by the community
Tekken Tag Tournament
Team synergy and tag combo routing are optimizable systems
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.
