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
Arcade western shooter narrated as a bounty hunter's tall tale.

Execution · Practiced Mastery
High-speed maze execution along planned score-maximizing routes.
Call of Juarez: Gunslinger leans Execution (Practiced Mastery); Pac-Man Championship Edition 2 leans Execution (Practiced Mastery).
Pac-Man Championship Edition 2 leans a little harder on execution, though the gap is small.
Call of Juarez: Gunslinger
Quick-draw duels and combo shooting demand precision
Pac-Man Championship Edition 2
Cornering at top speed under pressure decides scores
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Juarez: Gunslinger
Enemies are scripted gallery targets
Pac-Man Championship Edition 2
Ghost trains follow deterministic patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Juarez: Gunslinger
Minor enemy placement surprises first run
Pac-Man Championship Edition 2
Mazes and spawns are fixed per course
Pac-Man Championship Edition 2 leans a little harder on optimization, though the gap is small.
Call of Juarez: Gunslinger
Score routes, skill trees, duel timing knowledge
Pac-Man Championship Edition 2
Score routes and ghost-train herding are deeply plannable
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.
