All three assistants agreed on 3 of them
Pure Plumbing & Air, Roto-Rooter (Las Vegas), Active Plumbing (Las Vegas) were named by ChatGPT, Gemini, and Perplexity alike. Agreement across three systems that read different sources is a stronger observed pattern than appearing in only one system. In Las Vegas, that happened for 3 businesses.

The assistants disagreed on 1 of 6 questions
Asked the identical question about Las Vegas, 1 of 6 comparisons produced no shared business at all — three assistants, three separate shortlists. There is no single "AI answer" for this market to optimize against, which is why being named by one assistant tells a Las Vegas owner very little about the other two.
5.6% of answers named nobody at all
In 1 of 18 answers the assistant declined to recommend anyone and pointed the buyer at a directory or a list of things to check instead. Those are answers where no Las Vegas business won anything.
