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

Execution · Competitive PvP
Fast arena-fighter execution plus guessing games against a human opponent.

Execution · Competitive PvP
A movement-first multiplayer shooter where parkour aim duels decide fights.
Dragon Ball Z: Budokai Tenkaichi 3 leans Execution (Competitive PvP); Titanfall leans Execution (Competitive PvP).
Titanfall leans a little harder on execution, though the gap is small.
Dragon Ball Z: Budokai Tenkaichi 3
Combo timing, dashes and beam clashes demand fast hands
Titanfall
Wall-running gunfights demand elite aim and movement
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball Z: Budokai Tenkaichi 3
Versus humans, baiting counters and vanish wars is prediction
Titanfall
Human pilots adapt positioning and titan timing against you
Titanfall leans a little harder on variance, though the gap is small.
Dragon Ball Z: Budokai Tenkaichi 3
Almost nothing hidden once both rosters are known
Titanfall
Some uncertainty in titan drops and flanks
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 3
Character tiers and combo routes form a learnable layer
Titanfall
Loadouts and titan timing are a thin solvable layer
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.
