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

Execution · Competitive PvP
A 2D anime fighter testing combo execution and team-assist planning.
Dragon Ball GT: Final Bout leans Execution (Competitive PvP); Dragon Ball Z: Extreme Butouden leans Execution (Competitive PvP).
Dragon Ball Z: Extreme Butouden leans a little harder on execution, though the gap is small.
Dragon Ball GT: Final Bout
Combo inputs and meteor-counter timing decide exchanges
Dragon Ball Z: Extreme Butouden
2D combo strings and assist timing demand quick hands
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
Dragon Ball Z: Extreme Butouden
Human versus play rewards predicting habits; AI is scripted
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
Dragon Ball Z: Extreme Butouden
Deterministic systems leave little to chance
Dragon Ball Z: Extreme Butouden 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
Dragon Ball Z: Extreme Butouden
Team composition and assist synergy form the strategy 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.
