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.

Optimization · Practiced Mastery
A stealth-action adventure where Aveline swaps social personas to move through 18th-century New Orleans.

Optimization · Pure Optimization
A hybrid real-time and tactical action RPG in a digital city.
Assassin's Creed III: Liberation leans Optimization (Practiced Mastery); Transistor leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed III: Liberation
Lenient parkour and counter combat set a low ceiling
Transistor
Real-time and planned hybrid combat.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed III: Liberation
Guards follow patrol scripts without adapting
Transistor
Process enemies follow scripts.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed III: Liberation
Light patrol and notoriety randomness
Transistor
Limited randomness.
Transistor leans a little harder on optimization, though the gap is small.
Assassin's Creed III: Liberation
Persona disguise system and mission routing reward planning
Transistor
Function loadouts have deep optimization.
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.
