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
A wrestling game testing grapple/reversal timing and reading opponents in versus.
Dragon Ball Z: Budokai Tenkaichi 2 leans Execution (Competitive PvP); Legends of Wrestling II 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
Legends of Wrestling II
Grapple timing and reversal windows are the lead skill
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
Legends of Wrestling II
Human matches reward reading opponent grapple attempts
Legends of Wrestling II leans a little harder on variance, though the gap is small.
Dragon Ball Z: Budokai Tenkaichi 2
Full movesets are public knowledge
Legends of Wrestling II
Minor randomness in move outcomes
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball Z: Budokai Tenkaichi 2
A 120-character roster of matchup and item knowledge
Legends of Wrestling II
Move chaining and stamina management reward planning
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.
