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 · Pure Mechanics
A vertical bullet-hell shooter testing precise dodging and scoring chains.

Execution · Practiced Mastery
Memorising spawn patterns then executing them flawlessly under one-hit-death rules.
DonPachi leans Execution (Pure Mechanics); Super Contra leans Execution (Practiced Mastery).
DonPachi leans a little harder on execution, though the gap is small.
DonPachi
Precise dodging through dense bullet patterns defines play
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.
DonPachi
Solo - enemies follow fixed bullet patterns
Super Contra
Alien waves follow fixed spawn scripts
DonPachi leans a little harder on variance, though the gap is small.
DonPachi
Patterns fixed once memorized, minimal randomness
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.
DonPachi
Chaining and weapon choice maximize score
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.
