Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
DoDonPachi
Execution · Practiced Mastery
Cave's genre-defining bullet hell where survival is execution and score is a memorized chain route.
Metal Slug
Execution · Practiced Mastery
Twitch dodging and shooting layered over memorised arcade stage routes.
DoDonPachi leans Execution (Practiced Mastery); Metal Slug leans Execution (Practiced Mastery).

Axis by axis
Execution9 vs 8
DoDonPachi leans a little harder on execution, though the gap is small.
DoDonPachi
Threading dense bullet curtains demands pixel-perfect movement
Metal Slug
Dodging dense bullet patterns and precise shots carry every credit
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
DoDonPachi
Fixed scripted patterns, nothing adapts
Metal Slug
Enemies follow fixed arcade scripts, never adapt
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DoDonPachi
Near-fully deterministic once patterns are learned
Metal Slug
Spawns are nearly deterministic once a stage is learned
Optimization7 vs 6
DoDonPachi leans a little harder on optimization, though the gap is small.
DoDonPachi
Chain meter routing defines high-level play entirely
Metal Slug
One-credit clears come from memorising routes and spawn patterns
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.
