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
Balletic side-scrolling shooter about chaining stylish slow-motion gun acrobatics.
Mad Dog McCree leans Execution (Practiced Mastery); My Friend Pedro 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
My Friend Pedro
Slow-motion acrobatic gunplay rewards precise 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
My Friend Pedro
Enemies are static placements
Mad Dog McCree leans a little harder on variance, though the gap is small.
Mad Dog McCree
Some ambush order shuffling, quickly mapped
My Friend Pedro
Deterministic levels
My Friend Pedro leans a little harder on optimization, though the gap is small.
Mad Dog McCree
Memorising who pops out where is the real progression
My Friend Pedro
Score-chasing optimal routes and trick chains
