The lifespan decider
When specs are close, support length decides it — this is what each phone costs per month of safe use.
Category by category
The 400's screen is the better one — 6.55-inch amoled, 1.5k, 120hz, 5000 nits peak.
The Pixel 8a's Google Tensor G3 is simply the faster chip.
The 400 has the stronger camera system — same lens count, higher-grade sensors.
