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

Optimization · Practiced Mastery
A puzzle-leaning platformer testing perspective-flip problem solving more than reflexes.

Optimization · Practiced Mastery
A quest-stuffed 2.5D platformer where a pink-haired wild boy bites evil pigs to undo their curses.
Super Paper Mario leans Optimization (Practiced Mastery); Tomba! 2: The Evil Swine Return 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.
Super Paper Mario
Light platforming demands, well below mainline Mario
Tomba! 2: The Evil Swine Return
Grab-and-throw platforming with moderate timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Paper Mario
Enemies follow simple fixed patterns, no adaptation
Tomba! 2: The Evil Swine Return
Scripted pigs, no adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Paper Mario
Dimension-flip secrets are scripted-but-unknown until found
Tomba! 2: The Evil Swine Return
Fixed events; quests are deterministic.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Paper Mario
Solving levels via the 2D/3D flip mechanic is the core test
Tomba! 2: The Evil Swine Return
Interlocking 130-plus event quests reward sequencing.
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.
