I was a big fan of Claude. Even defending CC from all the haters on Discord. Then Anthropic started to play games and quality of the model dropped while the app became very unstable. (not about limits in my case as I'm not a vivecoder)

I really dislike Altman, but honestly Codex is far superior. And their models are better or at least as good. And they are much better for backend/low level/C++/CUDA IME. Codex CLI is simpler and lean. Perhaps because Codex was rewritten in Rust earlier this year while CC is still in TypeScript.
