Axis by axis
Execution3 vs 5
Zero Sievert leans harder on execution: Top-down gunfights reward aim and positioning
Reads0 vs 0
Even - both lean on reads about the same.
Variance6 vs 7
Zero Sievert leans harder on variance: Procedural maps, loot rolls, and unseen ambushes

Diablo IV leans harder on optimization: Paragon, aspects, and damage buckets are solvable theorycraft.
