head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Return to Monkey Island leans Optimization (Pure Optimization); Syberia 2 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.

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Return to Monkey Island
Lateral-thinking item puzzles require mapping cause and effect chains
Syberia 2
Environmental and mechanical puzzles reward patient logical mapping
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.
