Pixel 9a vs 400
It depends
Too close to call outright

Value Score: Pixel 9a 73 · 400 76 — methodology
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
Both displays are effectively the same class.
The Pixel 9a's Google Tensor G4 is simply the faster chip.
The 400 has the stronger camera system — same lens count, higher-grade sensors.
5,300mAh vs 5,100mAh — the 400 lasts longer between charges.
The Pixel 9a is supported until Apr 2032 — 11 months longer than the 400.
Pound for pound, these two are equally good deals.
