Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Rainbow Six Siege

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Rainbow Six Siege
Site rotations only; loadouts deterministic.
Rivals of Aether
Stage hazards add minor variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Rainbow Six Siege
Operator picks, gadget placement, and utility usage.
Rivals of Aether
Elemental mechanic interactions and matchup routing reward study
