head to head
Guns of Icarus Online asks more than Dragon Ball: Xenoverse 2, and the gap is reads.

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

Reads · Mind & Math
A team airship battler testing crew coordination and outmaneuvering human captains.
Dragon Ball: Xenoverse 2 leans Execution (Practiced Mastery); Guns of Icarus Online leans Reads (Mind & Math).
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
Guns of Icarus Online
Gunnery arcs and repair juggling need competent hands
Guns of Icarus Online leans clearly harder on reads.
Dragon Ball: Xenoverse 2
PvP opponents bait supers and punish habits
Guns of Icarus Online
Human captains feint, reposition and counter your ship tactics
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball: Xenoverse 2

Guns of Icarus Online
Cloud cover hides ships briefly, little else random
Guns of Icarus Online leans a little harder on optimization, though the gap is small.
Dragon Ball: Xenoverse 2
Build stats and skill loadouts shape every matchup
Guns of Icarus Online
Loadouts, role coordination and positioning are deeply plannable
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.
