Anthropic has RLed the shit out of their models to the extent that they give sub-par answers to general purpose questions. Google has great models but is institutionally incapable of building a cohesive product experience. They are literally shipping their org chart with Gemini (mediocre product), AI Overview (trash), AI Mode (outstanding but limited modality), Gemini for Google Workspace (steaming pile), Gemini on Android (meh), etc.

ChatGPT feels better to use, has the best implementation of memory, and is the best at learning your preferences for the style and detail of answers.
