head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Practiced Mastery
Capcom's polished CPS2 vertical shooter built around a charging lock-on bomb and tight scoring play.

Execution · Pure Mechanics
Comic-panel beat 'em up notorious for punishing health drain and tough fights.
19XX: The War Against Destiny leans Execution (Practiced Mastery); Comix Zone leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
19XX: The War Against Destiny
Capcom bullet density plus lock-on bomb timing
Comix Zone
Brutal one-life brawling demands clean play
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
19XX: The War Against Destiny
Boss patterns are fixed
Comix Zone
Enemies follow fixed attack scripts
19XX: The War Against Destiny leans a little harder on variance, though the gap is small.
19XX: The War Against Destiny
Little hidden once stages are studied
Comix Zone
Everything is placed and scripted
19XX: The War Against Destiny leans a little harder on optimization, though the gap is small.
19XX: The War Against Destiny
Charge-shot usage and scoring routes reward deep study
Comix Zone
Panel routes and item use are memorizable
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.
