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

A dark psychological point-and-click adventure driven by fixed puzzles and a disturbing story.

Optimization · Pure Optimization
A tactile toy-box puzzler testing playful experimentation with hidden mechanisms.
Fran Bow leans Optimization (Pure Optimization); Gnog 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.

Gnog
The toys are charming clockwork, not minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Each head's mechanisms are unknown until fiddled with
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Fixed puzzle solutions; fully solvable
Gnog
Discovering each contraption's interaction sequence is the puzzle
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.
