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 · Pure Optimization
Planning augmented routes through dense environments where augment investment and sequencing define efficiency.

Optimization · Practiced Mastery
The first Dishonored: a stealth-action playground of layered powers.
Deus Ex: Mankind Divided leans Optimization (Pure Optimization); Dishonored 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.
Deus Ex: Mankind Divided
Takedown timing and combat aim have a real ceiling
Dishonored
Blink timing and combat inputs matter.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deus Ex: Mankind Divided
Guards are scripted; no opponent models the player
Dishonored
Guard AI scripted, non-adaptive.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Deus Ex: Mankind Divided
Alert thresholds add some hidden-state wrinkle to infiltration
Dishonored
Patrol timings vary mildly.
Deus Ex: Mankind Divided leans a little harder on optimization, though the gap is small.
Deus Ex: Mankind Divided
Praxis allocation and approach sequencing optimise mission completion
Dishonored
Power combos and stealth routes solvable.
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.
