Metrics — cross-model comparison
All figures below are computed from the 329 analyzed articles (of 329 in the ledger) and the 12 verified spec rows. Sentiment and recommendation indices and author verdicts are measurements of the source articles and their authors — this site never rates a product. Detail pages: sentiment · verdicts · issues. Ledgers: claims vs measured · scores · issues.
