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.

Optimization · Practiced Mastery
Dimension-hopping spectacle platformer built on the classic arsenal-upgrade loop.

Execution · Practiced Mastery
A pastel platformer where Yoshi carries Baby Mario and perfect scores demand finding everything.
Ratchet & Clank: Rift Apart leans Optimization (Practiced Mastery); Super Mario World 2: Yoshi's Island leans Execution (Practiced Mastery).
Super Mario World 2: Yoshi's Island leans a little harder on execution, though the gap is small.
Ratchet & Clank: Rift Apart
Dodging, rift-tether mobility, and weapon aim.
Super Mario World 2: Yoshi's Island
Egg-aiming and flutter jumps for 100 percent scores
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ratchet & Clank: Rift Apart
Scripted enemies and setpieces only.
Super Mario World 2: Yoshi's Island
All enemies are scripted
Ratchet & Clank: Rift Apart leans a little harder on variance, though the gap is small.
Ratchet & Clank: Rift Apart
Unknown encounters on first run.
Super Mario World 2: Yoshi's Island
Collectibles hidden only until found
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Ratchet & Clank: Rift Apart
Weapon leveling and bolt economy reward planned play.
Super Mario World 2: Yoshi's Island
Perfect-score runs demand full collectible routing
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.
