Multiple models is a must, mostly due to the sometimes unpredictable variations in responses to specific situations/contexts/languages and frameworks. I find that Sonnet 4, Gemini Pro 2.5 are solid in comparison to newer models (especially Sonnet 4.5 which I find frequently to underperform). When one model is stuck in a loop, switching to a model like GPT-5 often breaks it but which model will work is subject to circumstance. P.S. I spend at least 3-4 hours a day in code-gen activities of various levels using Cursor as my primary IDE.
