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

Execution · Practiced Mastery
Arena fighting where builds and combo execution meet light PvP prediction.

Optimization · Practiced Mastery
An arcade soccer RPG testing timed special moves and team building.
Dragon Ball: Xenoverse 2 leans Execution (Practiced Mastery); Inazuma Eleven Strikers 2012 Xtreme leans Optimization (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 2
Combo strings and vanish timing need moderate hands
Inazuma Eleven Strikers 2012 Xtreme
Timed inputs for shots and tackles need moderate 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 2
PvP opponents bait supers and punish habits
Inazuma Eleven Strikers 2012 Xtreme
Versus matches involve reading opponent movement
Inazuma Eleven Strikers 2012 Xtreme leans a little harder on variance, though the gap is small.
Dragon Ball: Xenoverse 2
QQ Bang crafting and drop rates randomise builds
Inazuma Eleven Strikers 2012 Xtreme
Special-move outcomes and matchups add some chaos
Inazuma Eleven Strikers 2012 Xtreme leans a little harder on optimization, though the gap is small.
Dragon Ball: Xenoverse 2
Build stats and skill loadouts shape every matchup
Inazuma Eleven Strikers 2012 Xtreme
Team composition and special-move builds drive performance
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.
