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

Optimization · Practiced Mastery
Chaotic co-op kitchen game solved by ruthless division of labor.

Execution · Practiced Mastery
An indie love letter to arcade flight combat with relentless missile-dodging dogfights.
Overcooked leans Optimization (Practiced Mastery); Project Wingman leans Execution (Practiced Mastery).
Project Wingman leans a little harder on execution, though the gap is small.
Overcooked
Chopping, carrying, and plating under the clock
Project Wingman
Dense missile spam demands constant evasive flying and aim.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Overcooked
Kitchens don't adapt; teammates aren't opponents
Project Wingman
Enemy aces are scripted set pieces.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Overcooked
Order queue randomness within known sets
Project Wingman
Fixed missions; conquest mode adds light randomness.
Overcooked leans a little harder on optimization, though the gap is small.
Overcooked
Station assignment and task routing win stars
Project Wingman
Loadout choice and learned mission flow decide harder difficulties.
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.
