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

Optimization · Pure Optimization
The deepest optimization puzzle in the Infinity Engine lineage, rewarding encyclopedic knowledge of 2nd Edition AD&D systems.

Optimization · Pure Optimization
A Pathfinder system-mastery game where feat optimization and kingdom timeline routing determine survival.
Baldur's Gate II: Shadows of Amn leans Optimization (Pure Optimization); Pathfinder: Kingmaker 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.
Baldur's Gate II: Shadows of Amn
Pause-and-plan removes twitch entirely; micro-placement has marginal value
Pathfinder: Kingmaker
Real-time-with-pause removes twitch; timed kingdom events add pressure marginally
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Baldur's Gate II: Shadows of Amn
Enemies run scripted behaviour patterns, never modelling your tactics
Pathfinder: Kingmaker
All enemies and advisors follow scripted patterns without player modelling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Baldur's Gate II: Shadows of Amn
Loot randomization and enemy ability use create hidden-information layers
Pathfinder: Kingmaker
Hidden ability check thresholds and timed kingdom deadlines create unknowns
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Baldur's Gate II: Shadows of Amn
Mage spell sequences, dual-class builds and Spellhold routing define mastery
Pathfinder: Kingmaker
Pathfinder feat chains and kingdom management routing have known optimal solutions
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.
