Answer
StatefulSets manage identity; anti-affinity spreads replicas to avoid node failure impact.
Quick Answer
StatefulSets guarantee separate PVCs per Pod but don't control which nodes they land on. Two database replicas might still end up on the same physical node — risky if that node fails. Pod Anti-Affinity explicitly prevents two replicas from co-locating on the same node or zone, providing actual physical separation beyond just separate storage identities.
