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.

Execution · Practiced Mastery
An indie love letter to arcade flight combat with relentless missile-dodging dogfights.

Execution · Practiced Mastery
Plannable stealth routing punctuated by precise ballistic marksmanship.
Project Wingman leans Execution (Practiced Mastery); Sniper Elite III leans Execution (Practiced Mastery).
Project Wingman leans a little harder on execution, though the gap is small.
Project Wingman
Dense missile spam demands constant evasive flying and aim.
Sniper Elite III
Ballistic long shots demand steady, compensated aim
Sniper Elite III leans a little harder on reads, though the gap is small.
Project Wingman
Enemy aces are scripted set pieces.
Sniper Elite III
Enemy AI follows mappable alert and search routines
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Project Wingman
Fixed missions; conquest mode adds light randomness.
Sniper Elite III
Patrol details and wind vary slightly per attempt
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Project Wingman
Loadout choice and learned mission flow decide harder difficulties.
Sniper Elite III
Open maps reward planned routes, sound masking and relocation
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.
