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

Optimization · Pure Optimization
Noir stealth puzzler about rewiring buildings so guards defeat themselves.

Optimization · Pure Optimization
Comedy adventure puzzles solved by matching the right sticker to the right head.
Gunpoint leans Optimization (Pure Optimization); Stick it to the Man! 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.
Gunpoint
Jump timing matters occasionally, lightly
Stick it to the Man!
Simple platforming with no twitch ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gunpoint
Guards patrol on fixed scripts
Stick it to the Man!
Mind-reading is a story device, not opponent modelling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gunpoint
Levels fully visible and deterministic
Stick it to the Man!
Every gag and sticker puzzle is scripted
Gunpoint leans a little harder on optimization, though the gap is small.
Gunpoint
Crosslink rewiring puzzles have clean optimal solutions
Stick it to the Man!
Matching stickers to puzzle locks is the core test
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.
