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

Gorogoa leans Optimization (Pure Optimization); Professor Layton and the Curious Village leans Optimization (Pure Optimization).
Professor Layton and the Curious Village leans a little harder on execution, though the gap is small.
Gorogoa
Dragging panels requires no skill
Professor Layton and the Curious Village
Stylus taps only; no dexterity pressure at all
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gorogoa
No opponent exists
Professor Layton and the Curious Village
No opponent, adaptive or otherwise
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gorogoa
Solutions unknown on first encounter only
Professor Layton and the Curious Village
Puzzle answers are hidden until reasoned out, then fixed
Professor Layton and the Curious Village leans a little harder on optimization, though the gap is small.
Gorogoa
Each panel arrangement has one elegant solvable answer
Professor Layton and the Curious Village
Every brainteaser has one clean solvable answer
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.
