I have the same experience. I was pretty happy with gemini 2.5 pro and was barely using claude 3.7. Now I am strictly using claude 4 (sonnet mostly). Especially with tasks that require multi tool use, it nicely self corrects which I never noticed in 3.7 when I used it.

But it's different in conversational sense as well. Might be the novelty, but I really enjoy it. I have had 2 instances where it had very different take and kind of stuck with me.
