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

Sally Face
Mystery beats are hidden information until revealed
Tales of Monkey Island

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
