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

Execution · Practiced Mastery
Rhythm-infused action game of rock duo versus EDM empire boss fights.
Darksiders leans Execution (Practiced Mastery); No Straight Roads 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.
Darksiders
combo-driven combat with dodge timing
No Straight Roads
Dodging and attacking on the musical beat
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
No Straight Roads
Bosses follow rhythm-locked scripts
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
No Straight Roads
Patterns are fixed to the soundtrack
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
No Straight Roads
Learning each boss's beat-mapped moveset
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.
