I currently use ChatGPT 4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro for various personal and work-related tasks, and I often compare them on the same task. It’s really hard to decide which performs best overall for me. Sometimes one will be obviously better or worse for a relatively trivial reason, such as a longer context window or overeager censorship (looking at you for both, Gemini!). But usually, especially for the extended back-and-forth interactions that I find most useful, I am unable to state objectively which model is better.
