Saatva Memory Foam Pillow comes out ahead by a narrow margin (4.5 vs 4.7). The gap is mostly about side sleepers with average-to-broad shoulders — read the strengths below before deciding.
The Simply Cool is the resilient memory foam pick — bounces back faster than slow-rebound foam, with ice-fabric cooling cover.
The Saatva Memory Foam is the best-overall side sleeper pick — 5" loft and dual-density construction fill the shoulder gap.
