Has anyone tried asking the exact same product questions to both ChatGPT 5.1 and Gemini? I did this twice today with wildly different results. In one case I was comparing capabilities and suggestions on audio equipment, being very specific in the setup, the models, and my goals. It was completely different in the results. I was comparing objective metrics and product specifications.

I plan on doing this every time now because ChatGPT gets things wrong constantly, apologizes and changes its facts, while Gemini is cheerful and positive like a salesperson.

These things have given me tremendous doubt after one year of usage.
