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
Fan-built ground-up remake of Half-Life with a reimagined Xen.

Execution · Practiced Mastery
Greedy platformer where Wario charges through Kitchen Island hoarding coins and treasure.
Black Mesa leans Execution (Practiced Mastery); Wario Land: Super Mario Land 3 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.
Black Mesa
Classic FPS aim and platforming sequences
Wario Land: Super Mario Land 3
Platforming jumps and shoulder-charge timing
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
Wario Land: Super Mario Land 3
Entirely scripted single-player levels
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
Wario Land: Super Mario Land 3
Hidden exits and treasures unknown on first play
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
Wario Land: Super Mario Land 3
Coin hoarding and treasure routing drive the best ending
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.
