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.

Optimization · Practiced Mastery
Planning squad approaches to scripted missions where one mistake kills.

Execution · Practiced Mastery
Balancing ballistics execution with patrol timing to eliminate targets without triggering coordinated alerts.
Hidden & Dangerous 2 leans Optimization (Practiced Mastery); Sniper Elite 4 leans Execution (Practiced Mastery).
Sniper Elite 4 leans a little harder on execution, though the gap is small.
Hidden & Dangerous 2
Deliberate aim and stealth movement punish sloppy hands
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.
Hidden & Dangerous 2
German AI follows patrol scripts, not adapting to you
Sniper Elite 4
Axis soldiers follow scripted patrol cycles without modelling the player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hidden & Dangerous 2
Patrol routes and enemy positions are unknown first attempt
Sniper Elite 4
Wind direction and enemy patrol timing add first-run uncertainty
Hidden & Dangerous 2 leans a little harder on optimization, though the gap is small.
Hidden & Dangerous 2
Squad planning, loadouts and approach routing decide missions
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.
