Gemini is the only model which tells me when it's a good time to stop chatting because either it can't find a solution or because it dislikes my solution (when I actively want to neglect security).
And the context length is just amazing. When ChatGPT's context is full, it totally forgets what we were chatting about, as if it would start an entirely new chat.
Gemini lacks the tooling, there ChatGPT is far ahead, but at its core, Gemini feels like a better model.
