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 · Pure Optimization
The 2002 Total War pairing turn-based medieval empire management with massive real-time battles.

Optimization · Pure Optimization
A tactical RPG testing positioning and turn prediction on a grid battlefield.
Medieval: Total War leans Optimization (Pure Optimization); Vandal Hearts II leans Optimization (Pure Optimization).
Medieval: Total War leans a little harder on execution, though the gap is small.
Medieval: Total War
Real-time battle control rewards quick unit handling
Vandal Hearts II
Simultaneous-turn combat has no twitch input
Vandal Hearts II leans a little harder on reads, though the gap is small.
Medieval: Total War
Multiplayer battles add human feints; campaign AI is scripted
Vandal Hearts II

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Medieval: Total War
Battle dice, loyalty and event cards add noise
Vandal Hearts II
Hit chances add bounded randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Medieval: Total War
Campaign economy and battlefield doctrine are deeply learnable
Vandal Hearts II
Unit positioning, builds and the prediction system win battles
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.
