Fourteen AI models were asked for product analytics platform six ways each, on behalf of a small, a mid-market and an enterprise B2B company: 252 answers, in which a judge labeled 64 products. Three of them carry at least 10 labels and a first choice, and are ranked. This guide walks the top three in the order the mid-market standing puts them, with what the models said for and against each, in their words. Amplitude leads at 46% of first choices, a clear leader.
| Product | First-choice share | Negative rate | Labels | Leads for | Quadrant | |
|---|---|---|---|---|---|---|
| 1 | 46% | 13% | 71 | Mid-market, Enterprise | endorsed leader | |
| 2 | 33% | 6% | 71 | Small business | endorsed leader | |
| 3 | 22% | 16% | 75 | none | accepted challenger |
The full standing, every product with 10 labels or more, is on the category page, with the products at zero and the ones warned against.
A product is on the record because a model named it in an answer and the judge labeled the naming: first choice, alternative, mention, caution or warning, each with the sentence it came from. 64 products were named for product analytics platform this edition.
A product is ranked once it carries 10 labels in a segment and at least one first choice there. Below that it is named but not ranked, and it says so on its page. The vendor table that folds spellings into products is versioned; this page was scored under v2026-11-09.1.
The same categories are asked again with nothing changed to measure how much an answer moves on its own. A change in share smaller than the floor is not reported as a change. The repeat, model by model.
