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
The 1981 arcade classic of climbing girders and dodging barrels.

Execution · Practiced Mastery
A classic frenetic shooter that rewards fast reflexes and mastering enemy patterns.
Donkey Kong leans Execution (Practiced Mastery); The Ultimate Doom 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.
Donkey Kong
Frame-tight jumps over barrels under arcade pressure
The Ultimate Doom
twitch aim and movement drive combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong
Fixed arcade patterns, nothing adapts
The Ultimate Doom
fixed demon patterns, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong
Barrel bounces add slight unpredictability
The Ultimate Doom
minor spawn and drop randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong
Stage patterns and score routes fully learnable
The Ultimate Doom
weapon routing and glory-kill loops solvable
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.
