Most-compared models

Where a model appears in many pairs, it's usually the one every other model in its class gets compared against — its “Appears in” count links to every pair it belongs to.

How these are written
A pair gets a page only when both products have a full spec sheet on file — not when one is guessed at. Where a maker doesn't publish a figure, the row says so rather than carrying an estimate, and a pair with no tracked price on either side compares specifications alone.
