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

Execution · Competitive PvP
Arena-fighter execution and couch-versus prediction across an enormous anime roster.

Execution · Competitive PvP
On-the-ball flair and one-on-one deception in small-sided street matches.
Dragon Ball Z: Budokai Tenkaichi 2 leans Execution (Competitive PvP); FIFA Street 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 2
Beam clashes, vanish timing and arena movement reward fast hands
FIFA Street
Flair moves and trick timing decide 4-on-4 duels
Dragon Ball Z: Budokai Tenkaichi 2 leans a little harder on reads, though the gap is small.
Dragon Ball Z: Budokai Tenkaichi 2
Versus friends, baiting transformations and dodges matters
FIFA Street
Beating a human marker is feint-versus-anticipation
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 2
Full movesets are public knowledge
FIFA Street
Compact courts keep outcomes deterministic
Dragon Ball Z: Budokai Tenkaichi 2 leans a little harder on optimization, though the gap is small.
Dragon Ball Z: Budokai Tenkaichi 2
A 120-character roster of matchup and item knowledge
FIFA Street
Reputation grind and team building are light 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.
