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

Gorogoa leans Optimization (Pure Optimization); Professor Layton and the Diabolical Box leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Gorogoa
Dragging panels requires no skill
Professor Layton and the Diabolical Box
Stylus taps - zero dexterity demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

No opponent exists
Professor Layton and the Diabolical Box
No opponent; a parade of standalone brainteasers
Gorogoa leans a little harder on variance, though the gap is small.
Gorogoa
Solutions unknown on first encounter only
Professor Layton and the Diabolical Box
Puzzles are fixed; only their first encounter surprises
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Gorogoa
Each panel arrangement has one elegant solvable answer
Professor Layton and the Diabolical Box
Each brainteaser has one clean logical solution to find
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.
