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
Zelda-meets-God-of-War action adventure starring the horseman War.

Execution · Practiced Mastery
Pulpy vampire-hunting brawler built on chunky arena combat.
Darksiders leans Execution (Practiced Mastery); Evil West leans Execution (Practiced Mastery).
Evil West leans a little harder on execution, though the gap is small.
Darksiders
combo-driven combat with dodge timing
Evil West
Combo juggling and dodge timing in arena fights
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Darksiders
enemies are scripted
Evil West
Monsters attack on fixed patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Darksiders
world and bosses are fixed
Evil West
Linear levels, fully deterministic
Darksiders leans a little harder on optimization, though the gap is small.
Darksiders
Zelda-style dungeons and upgrade routing
Evil West
Upgrade picks and learned encounter waves
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.
