What the record shows, beyond the standings

Findings computed from the September 2026 Edition and rebuilt with every edition: how stable one answer is, how the answer changes with the buyer, and what the answers cite. Each page states its denominators and links to the pages that carry the evidence.

Repeat measurement

The same question, asked twice

Asked again with nothing changed, the models moved their own first choice 68% of the time, and the leader still held in 7 of 10 categories.

Buyer segments

The buyer's size changes the answer

In 39 of 41 categories the leader differs between small business, mid-market and enterprise buyers. The same category, three standings.

Citations

What the answers cite

Four of the twelve models return a source list; across their 2,617 answers, 24% of the 32,826 citations point at a vendor's own site and 7% at a review site.

How these are made

Nothing on these pages is typed. Each figure is computed from the published edition at build time, the same way every standing on the site is, so a research page cannot disagree with the category page it draws on. From the second edition on, a page that compares editions joins this list.
