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
Tests fast maze execution and ghost-train routing under randomized attack pressure.

Execution · Practiced Mastery
Balancing ballistics execution with patrol timing to eliminate targets without triggering coordinated alerts.
Pac-Man 99 leans Execution (Practiced Mastery); Sniper Elite 4 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.
Pac-Man 99
Maze steering at speed under jammer pressure decides survival
Sniper Elite 4
Long-range ballistics, bullet drop, and wind compensation are the core demand
Pac-Man 99 leans a little harder on reads, though the gap is small.
Pac-Man 99
98 opponents are anonymous noise, not readable minds
Sniper Elite 4
Axis soldiers follow scripted patrol cycles without modelling the player
Pac-Man 99 leans a little harder on variance, though the gap is small.
Pac-Man 99
Incoming attacks and ghost spawns randomize each match
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.
Pac-Man 99
Ghost-train routing and target strategies have known best lines
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.
