I would pick the one that is the most polite and makes the least syntactical and grammatical errors to be the AI always; most humans are absolutely terrible at formulating anything coherent so it's a safe bet that the ones who actually form correct sentences are AI. Many (most I see online or on the street) humans talk like Markov Chains (check your kid's snapchat for examples) or, at best, very early transformers (tons of repetition, getting stuck and not all that coherent).
