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
Routing and executing perfect scoring runs through scripted shooting arenas.

Execution · Practiced Mastery
A classic frenetic shooter that rewards fast reflexes and mastering enemy patterns.
The Club 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.
The Club
Chaining kills without dropping combo demands fast precise aim
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.
The Club
Enemy spawns are scripted and memorisable
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.
The Club
Nothing random once spawn layouts are learned
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.
The Club
Score routes through each arena are the real puzzle
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.
