This has been my experience also, but i've been using everything (Claude code, open code, copilot, etc...) It's impressive when I ask it to do something I don't know how like some python apps, but when it's in my stack I have to constantly stop it mid processing and ask it to fix something. I'm still validanting the plan and rewriting a lot of the code because the quality just is not there yet.

And for the most part I use either opus or sonnet, but for planning sometimes I switch to chatgpt since I think claude is too blunt and does not ask enough questions. I also have local setups with OLlama and have tried for personal projects some kimi models. The results are the same for all, but again claude models are slighly better.
