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
Aiming at bloon waves while solving a tower-defense upgrade economy first-person.

Execution · Practiced Mastery
Day-glo traversal shooter where staying on rails and walls keeps your style and survival up.
Apes vs Helium leans Execution (Practiced Mastery); Sunset Overdrive 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.
Apes vs Helium
An aimbot popping every bloon would trivialise the waves
Sunset Overdrive
Grind-rail momentum and mid-air shooting reward clean hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Apes vs Helium
Bloons follow fixed tracks, nothing adapts
Sunset Overdrive
Mutant hordes are pattern-driven, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Apes vs Helium
Wave composition is learnable, little stays hidden
Sunset Overdrive
Horde mode spawns mix things up slightly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Apes vs Helium
Upgrade and class economy against known waves is solvable
Sunset Overdrive
Amp builds, traversal lines, and style multipliers are 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.
