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

A notoriously difficult comedy adventure where Rincewind the inept wizard must rid Ankh-Morpork of a dragon.

Optimization · Pure Optimization
Comedic point-and-click adventure of Guybrush Threepwood, hand-drawn at its peak.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Discworld
Point-and-click; no manual ceiling.
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.

Ankh-Morpork's citizens are scripted gag dispensers.

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Discworld
Byzantine item chains are brutal but fully solvable.
The Curse of Monkey Island
inventory logic puzzles are fully solvable
