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

Optimization · Systems & Chaos
A casual linking puzzle testing move efficiency against randomized boards.

Optimization · Practiced Mastery
A meta puzzle box testing curiosity and one-time discovery more than any repeatable skill.
Pokémon Café Mix leans Optimization (Systems & Chaos); Pony Island leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Pokémon Café Mix
Tracing icon links cleanly matters slightly under move limits
Pony Island
Light arcade hopping segments with low demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Pokémon Café Mix
No opponent in serving pastries
Pony Island
The devil's tricks are authored scripts, not adaptation
Pokémon Café Mix leans a little harder on variance, though the gap is small.
Pokémon Café Mix
Board layouts and icon drops are random per attempt
Pony Island
Meta twists are hidden information that spend on first reveal
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Pokémon Café Mix
Staff choice and move efficiency decide tight levels
Pony Island
Code-tinkering puzzles have fixed discoverable solutions
