head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

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

Execution · Practiced Mastery
Looking Glass's 1996 squad-command sim of powered-armor combat on alien battlefields.
Payday 2 leans Execution (Practiced Mastery); Terra Nova: Strike Force Centauri 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.
Payday 2
Sustained gunfights and stealth execution under pressure
Terra Nova: Strike Force Centauri
Piloting powered armor and aiming under fire is demanding
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
Terra Nova: Strike Force Centauri
Enemy forces follow mission scripts, never adapt
Payday 2 leans a little harder on variance, though the gap is small.
Payday 2
Random vault locations, guard patrols, and escrow rolls
Terra Nova: Strike Force Centauri
Unknown enemy placements on first mission attempts
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Payday 2
Skill builds and stealth route planning per heist
Terra Nova: Strike Force Centauri
Squad orders, loadouts and approach routes are plannable
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.
