Sources
Product capabilities and pricing are checked against official vendor documentation, product pages and first-party marketplace listings. Bare source links are kept close to the comparison and no campaign parameters are added.
Observed behavior
First-person observations appear only when the stated product surface was actually used. A public quiz check, guided tour and authenticated builder test are different evidence levels and are described separately.
Scores and lanes
Scores follow the published 100-point method. Lanes describe the clearest practical fit for each tool and are reviewed whenever a material product change affects the recommendation.
Updates
Dates are refreshed only after review. Pricing receives a scheduled quarterly check. Material edits are added to the change log with the date and reason.
