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
Memorising spawn patterns then executing them flawlessly under one-hit-death rules.
Call of Juarez: Gunslinger leans Execution (Practiced Mastery); Super Contra leans Execution (Practiced Mastery).
Super Contra leans a little harder on execution, though the gap is small.
Call of Juarez: Gunslinger
Quick-draw duels and combo shooting demand precision
Super Contra
One-hit deaths demand precise dodging and constant accurate fire
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
Super Contra
Alien waves follow fixed spawn 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
Super Contra
Nothing random once spawn patterns are memorised
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
Super Contra
Memorising spawns and weapon routes is half the run
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.
