Which electric toothbrushe does Claude recommend first?
Claude's current #1 for electric toothbrushes is shown in the model column of the full ranking.
How are these rankings measured?
We ask each model the same buying questions on every run (1,680 queries this period), record the full answers, and score each named brand 0-100 by how early and how consistently it appears. Every question runs through the official model APIs, with web search on, not through the consumer chat apps, so nothing is personalized to a user. Each model is scored independently; the consensus blends all 4.
Do the AI models agree with each other?
Not fully. The four models crown 2 different #1s at the latest close, and several brands carry wide spreads. That is the gap between their best and worst model rank. That disagreement is a finding, not noise: different models read different sources.
This is the guide. The record has more.
