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

Lane defense classic about managing a sun economy against shambling waves.

Optimization · Pure Optimization
Tests lateral puzzle deduction to uncover a button panel's hidden endings.
Plants vs. Zombies leans Optimization (Pure Optimization); Please, Don't Touch Anything 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.

Clicking to plant, minimal pressure
Please, Don't Touch Anything
Pressing buttons takes no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Zombie waves follow set compositions
Please, Don't Touch Anything
