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

Optimization · Systems & Chaos
Composing morale-aware armies and spell loadouts to solve scripted hex-grid encounters.

Optimization · Pure Optimization
Lane-defense economy optimization against semi-randomised zombie waves.
King's Bounty II leans Optimization (Systems & Chaos); Plants vs. Zombies 2: It's About Time 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.
King's Bounty II
Turn-based hex grid; no timing inputs
Plants vs. Zombies 2: It's About Time
Tapping plants quickly only matters in surge moments
King's Bounty II leans a little harder on reads, though the gap is small.
King's Bounty II
Enemy AI is scripted; unit targeting is fixed-priority
Plants vs. Zombies 2: It's About Time
Zombie waves are announced patterns, not minds
King's Bounty II leans a little harder on variance, though the gap is small.
King's Bounty II
Spell proc rates and random loot create variance across encounters
Plants vs. Zombies 2: It's About Time
Wave compositions and plant-food drops add per-level randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
King's Bounty II
Army composition, leadership allocation, and morale management are planned
Plants vs. Zombies 2: It's About Time
Lawn economy and plant placement are the solvable core
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.
