"Cursor" Grok has the exact same (non-)personality as Claude.
GPT has the same performance. And performance is definitely a commodity. Why wouldn't it be?
I don’t think GPT Astra is as good as Opus 5.5, it’s very noticeable how pedantic and poor at intuiting things it is to me. It often calls things done when Claude would keep working on them, and doesn’t seem to have as good of an eye - often leaving clear visual defects and calling things done.
