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.

Execution · Practiced Mastery
Lightgun quick-draw reflexes against memorisable filmed ambush sequences.

Execution · Practiced Mastery
Retro ninja platformer that flips from linear levels into a time-hopping metroidvania.
Mad Dog McCree leans Execution (Practiced Mastery); The Messenger leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mad Dog McCree
Quick-draw lightgun accuracy under strict timers
The Messenger
cloudstep chains demand precise aerial control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mad Dog McCree
Outlaws appear in filmed, fixed sequences
The Messenger
enemies and bosses are fully scripted
Mad Dog McCree leans a little harder on variance, though the gap is small.
Mad Dog McCree
Some ambush order shuffling, quickly mapped
The Messenger
deterministic level design
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mad Dog McCree
Memorising who pops out where is the real progression
The Messenger
upgrade economy and late-game route knowledge
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.
