Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Black MesaUnreal
Axis by axis
Execution6 vs 6
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Black Mesa
Classic FPS aim and platforming sequences
Unreal
Aim and dodging against fast Skaarj carry encounters
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Black Mesa
Marines and aliens follow set scripts
Unreal
Scripted alien AI never adapts to you
Variance2 vs 2
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Black Mesa
Minor enemy placement surprises first run
Unreal
First-run level surprises map out quickly
Optimization6 vs 6
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Black Mesa
Route, resource, and encounter knowledge
Unreal
Weapon choice, secrets, and route knowledge trivialise replays
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.
