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

Execution · Practiced Mastery
An open-city sequel deepening freeflow combat and predator gadget play.

Execution · Practiced Mastery
A campy hack-and-slash starring a cheerleader mowing down zombies with a chainsaw.
Batman: Arkham City leans Execution (Practiced Mastery); Lollipop Chainsaw 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.
Batman: Arkham City
Combo chains and counters need timing.
Lollipop Chainsaw
Combo execution and crowd-control timing
Batman: Arkham City leans a little harder on reads, though the gap is small.
Batman: Arkham City
Enemies scripted, not adaptive.
Lollipop Chainsaw
Scripted zombie hordes
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Batman: Arkham City
Fixed encounters and challenges.
Lollipop Chainsaw
Deterministic encounters
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Batman: Arkham City
Gadget combos and challenge maps learnable.
Lollipop Chainsaw
Combo unlock economy and score-chaining strategy
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.
