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.

Optimization · Systems & Chaos
An inspection-procedure test of judging hidden infections under base-building pressure.

Optimization · Pure Optimization
Growing a floating base by solving resource chains and research order against scripted ocean threats.
Quarantine Zone: The Last Check leans Optimization (Systems & Chaos); Raft leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Quarantine Zone: The Last Check
Inspecting survivors and managing defenses needs no dexterity
Raft
Shark hook-attacks require minimal timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Quarantine Zone: The Last Check
Survivors are generated cases, not adapting deceivers
Raft
Shark and seagull AI are scripted with no player modelling
Quarantine Zone: The Last Check leans a little harder on variance, though the gap is small.
Quarantine Zone: The Last Check
Each arrival's infection status is hidden until inspected
Raft
Island loot tables and resource drift introduce randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Quarantine Zone: The Last Check
Mastering inspection rules and base economy converges to procedure
Raft
Raft expansion, food chains, and research order are solvable systems
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.
