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
A classic frenetic shooter that rewards fast reflexes and mastering enemy patterns.

Execution · Practiced Mastery
A speedrun shooter testing teleport execution against optimised level routes.
The Ultimate Doom leans Execution (Practiced Mastery); Velocity Ultra 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.
The Ultimate Doom
twitch aim and movement drive combat
Velocity Ultra
Teleport precision at full throttle defines perfect medals
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Ultimate Doom
fixed demon patterns, no adaptation
Velocity Ultra
Hazards are fixed level geometry, not minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Ultimate Doom
minor spawn and drop randomness
Velocity Ultra
Levels are identical every attempt
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
The Ultimate Doom
weapon routing and glory-kill loops solvable
Velocity Ultra
Route planning through bomb switches is half the score chase
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.
