head to head
Payday 2 asks more than Ziggurat, and the gap is optimization.

Execution · Practiced Mastery
Loot-driven co-op heist shooter where builds and route knowledge make perfect crimes.

Execution · Twitch Chaos
A fast first-person roguelike of wand-blasting through randomised dungeon arenas.
Payday 2 leans Execution (Practiced Mastery); Ziggurat leans Execution (Twitch Chaos).
Ziggurat leans a little harder on execution, though the gap is small.
Payday 2
Sustained gunfights and stealth execution under pressure
Ziggurat
Fast circle-strafing wand combat in arena rooms
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Payday 2
Cops and guards follow spawn scripts
Ziggurat
Monster AI never adapts
Ziggurat leans a little harder on variance, though the gap is small.
Payday 2
Random vault locations, guard patrols, and escrow rolls
Ziggurat
Random rooms, weapons, and perk draws each run
Payday 2 leans clearly harder on optimization.
Payday 2
Skill builds and stealth route planning per heist
Ziggurat
Perk evaluation and enemy priority knowledge
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.
