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
Planning a kill order and landing extreme-range ballistic shots against scripted patrols.

Optimization · Practiced Mastery
FPS scenarios converted into solvable sequencing puzzles by stopped time.
Sniper Ghost Warrior Contracts 2 leans Execution (Practiced Mastery); SuperHot leans Optimization (Practiced Mastery).
Sniper Ghost Warrior Contracts 2 leans a little harder on execution, though the gap is small.
Sniper Ghost Warrior Contracts 2
Aimbot trivialises the long-range ballistic shots that define it
SuperHot
Time-stops-when-you-stop removes most twitch pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sniper Ghost Warrior Contracts 2
Enemy patrols follow fixed scripts, never adapting to your tactics
SuperHot
Red guys follow spawn scripts, not minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sniper Ghost Warrior Contracts 2
Wind and patrol layouts are unknown until scouted, then fixed
SuperHot
Spawn order is unknown on a first attempt only
SuperHot leans a little harder on optimization, though the gap is small.
Sniper Ghost Warrior Contracts 2
Planning routes, shot order and contract objectives is half the game
SuperHot
Each level is a solvable movement-and-kill-order puzzle
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.
