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
Claustrophobic post-apocalyptic shooter where bullets double as currency.

Optimization · Practiced Mastery
Managing scarce resources between stations while clearing scripted infected with careful shots.
Metro 2033 leans Execution (Practiced Mastery); The Final Station leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Metro 2033
scarce-ammo gunfights punish sloppy aim
The Final Station
Headshotting infected swarms with scarce ammo demands steady aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metro 2033
mutants and bandits follow scripts
The Final Station
Infected follow simple scripted rushes, never adapt
The Final Station leans a little harder on variance, though the gap is small.
Metro 2033
hidden moral points and supplies first run
The Final Station
Unknown station layouts and loot until explored, then mapped
The Final Station leans a little harder on optimization, though the gap is small.
Metro 2033
ammo-as-currency economy and stealth routing
The Final Station
Rationing ammo, food and passenger care is the real game
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.
