head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Arcade western shooter narrated as a bounty hunter's tall tale.

Execution · Practiced Mastery
A classic arcade Star Wars flight shooter where gold medals demand clean, fast, memorized runs.
Call of Juarez: Gunslinger leans Execution (Practiced Mastery); Star Wars: Rogue Squadron 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.
Call of Juarez: Gunslinger
Quick-draw duels and combo shooting demand precision
Star Wars: Rogue Squadron
Tight flying and precise blaster aim drive medal runs.
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
Star Wars: Rogue Squadron
TIE fighters follow fixed flight scripts.
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
Star Wars: Rogue Squadron
Missions are entirely fixed and rememberable.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Juarez: Gunslinger
Score routes, skill trees, duel timing knowledge
Star Wars: Rogue Squadron
Gold-medal criteria reward optimized routes and target priorities.
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.
