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
Ninja Theory's stylish-action reboot with angel-demon stance switching through a shifting Limbo.
Darksiders leans Execution (Practiced Mastery); DmC: Devil May Cry leans Execution (Practiced Mastery).
DmC: Devil May Cry leans a little harder on execution, though the gap is small.
Darksiders
combo-driven combat with dodge timing
DmC: Devil May Cry
Angel/demon stance weaving is demanding but softer than mainline
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
DmC: Devil May Cry
Color-coded enemies dictate fixed answers
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
DmC: Devil May Cry
Limbo levels are authored spectacle, not random
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Darksiders
Zelda-style dungeons and upgrade routing
DmC: Devil May Cry
