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 · Practiced Mastery
Twitchy cover-shooter rooms that reward drilled execution and memorised routes.

Execution · Practiced Mastery
Balancing ballistics execution with patrol timing to eliminate targets without triggering coordinated alerts.
Not a Hero leans Execution (Practiced Mastery); Sniper Elite 4 leans Execution (Practiced Mastery).
Not a Hero leans a little harder on execution, though the gap is small.
Not a Hero
Slide-cancels, snap cover and reload timing decide every room
Sniper Elite 4
Long-range ballistics, bullet drop, and wind compensation are the core demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Not a Hero
Enemies follow fixed behaviours, nothing adapts to you
Sniper Elite 4
Axis soldiers follow scripted patrol cycles without modelling the player
Sniper Elite 4 leans a little harder on variance, though the gap is small.
Not a Hero
Minor enemy spawn jitter, levels otherwise deterministic
Sniper Elite 4
Wind direction and enemy patrol timing add first-run uncertainty
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Not a Hero
Learning room layouts and routing kills enables full-clear runs
Sniper Elite 4
Synchronised shot timing and route planning reward methodical preparation
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.
