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 · Practiced Mastery
An arena fighter mixing combo execution, build grinding and human prediction online.

Execution · Competitive PvP
A wrestling game testing grapple/reversal timing and reading opponents in versus.
Dragon Ball: Xenoverse leans Execution (Practiced Mastery); 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: Xenoverse
3D arena combos, vanishes and ki management need practiced hands
Legends of Wrestling II
Grapple timing and reversal windows are the lead skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball: Xenoverse
Online PvP rewards predicting human mixups; PvE is scripted
Legends of Wrestling II
Human matches reward reading opponent grapple attempts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball: Xenoverse
Skill drops from missions roll randomly
Legends of Wrestling II
Minor randomness in move outcomes
Dragon Ball: Xenoverse leans a little harder on optimization, though the gap is small.
Dragon Ball: Xenoverse
Build crafting and attribute allocation shape PvP viability
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.
