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
Comic-panel beat 'em up notorious for punishing health drain and tough fights.

Execution · Pure Mechanics
A bullet-hell shooter testing precision dodging and scoring through scripted patterns.
Comix Zone leans Execution (Pure Mechanics); Danmaku Unlimited 3 leans Execution (Pure Mechanics).
Danmaku Unlimited 3 leans a little harder on execution, though the gap is small.
Comix Zone
Brutal one-life brawling demands clean play
Danmaku Unlimited 3
Precise dodging through dense bullet patterns is everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Comix Zone
Enemies follow fixed attack scripts
Danmaku Unlimited 3
Bosses fire scripted patterns, not adaptive
Danmaku Unlimited 3 leans a little harder on variance, though the gap is small.
Comix Zone
Everything is placed and scripted
Danmaku Unlimited 3
Minor item randomness, patterns deterministic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Comix Zone
Panel routes and item use are memorizable
Danmaku Unlimited 3
Scoring systems and ship choice optimize underneath
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.
