head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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

Execution · Practiced Mastery
Shooter-platforming crossed with base defense, testing weapon execution and turret planning.
Dragon Ball: Xenoverse leans Execution (Practiced Mastery); Ratchet & Clank: Full Frontal Assault leans Execution (Practiced Mastery).
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
Ratchet & Clank: Full Frontal Assault
Weapon juggling and movement carry the defense waves
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
Ratchet & Clank: Full Frontal Assault
Competitive raids against humans reward predicting attack lanes
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
Ratchet & Clank: Full Frontal Assault
Wave compositions are mostly known after few runs
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball: Xenoverse
Build crafting and attribute allocation shape PvP viability
Ratchet & Clank: Full Frontal Assault
Turret placement and node economy are plannable 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.
