How this is made

Built from what 4 AI models (Gemini · Perplexity · Claude · ChatGPT) recommend across the catalog, layered with company reviewer takes, press coverage, marketing-honesty checks and price positioning. The short answer and verdict are derived from where those signals diverge — not written by hand for either brand.

So which brand?

Breadth vs focus — and the right answer depends on the shelf.

We don’t crown a winner. Globally they may both be top-tier; locally, the category can flip the answer. Pick the brand that’s strong where you’re actually shopping — when a brand doesn’t compete in a category, we leave it blank rather than invent a rank.
