head to head
Dragon Ball Z: Budokai Tenkaichi 3 asks more than Street Fighter, and the gap is optimization.

Execution · Competitive PvP
Fast arena-fighter execution plus guessing games against a human opponent.

Execution · Competitive PvP
Wrestling crude controls to land specials while outguessing a human opponent.
Dragon Ball Z: Budokai Tenkaichi 3 leans Execution (Competitive PvP); Street Fighter 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 Z: Budokai Tenkaichi 3
Combo timing, dashes and beam clashes demand fast hands
Street Fighter
Notoriously stiff inputs make landing specials the real fight
Dragon Ball Z: Budokai Tenkaichi 3 leans a little harder on reads, though the gap is small.
Dragon Ball Z: Budokai Tenkaichi 3
Versus humans, baiting counters and vanish wars is prediction
Street Fighter
Human versus rounds still reward bait and punish
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball Z: Budokai Tenkaichi 3
Almost nothing hidden once both rosters are known
Street Fighter
Nothing hidden between two visible fighters
Dragon Ball Z: Budokai Tenkaichi 3 leans clearly harder on optimization.
Dragon Ball Z: Budokai Tenkaichi 3
Character tiers and combo routes form a learnable layer
Street Fighter
Tiny moveset leaves little system to solve
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.
