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

Point-and-click; no dexterity required
The Curse of Monkey Island
pointing and clicking only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
