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

Execution · Competitive PvP
A rough anime fighter testing input timing and second-guessing a human opponent.

Execution · Competitive PvP
An anime arena fighter testing combo execution and versus-match prediction.
Dragon Ball GT: Final Bout leans Execution (Competitive PvP); Saint Seiya: Soldiers' Soul leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball GT: Final Bout
Combo inputs and meteor-counter timing decide exchanges
Saint Seiya: Soldiers' Soul
Combos, dashes and burst timing carry every exchange
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball GT: Final Bout
Human opponents bait and adapt in versus play
Saint Seiya: Soldiers' Soul
Human versus matches reward predicting blocks and seventh-sense baits
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball GT: Final Bout
Nothing hidden once movesets are known
Saint Seiya: Soldiers' Soul
Nothing hidden once both rosters are known
Saint Seiya: Soldiers' Soul leans a little harder on optimization, though the gap is small.
Dragon Ball GT: Final Bout
Small roster and shallow systems cap the study layer
Saint Seiya: Soldiers' Soul
Character matchups and cosmo-meter management form a learnable layer
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.
