Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
A gentle turn-based system easily solved by build and gear choices.

South Park: The Stick of Truth
Timed attack and block prompts add light input demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
