Agreed, these are my vibes too. It feels much better to do planning and strategy and architecture etc. with Opus 4.7 than GPT-5.5. GPT just feels like a robot that gets instructions and does exactly that. Opus feels like an almost human that sometimes has actually good ideas and pushes back on bad ideas.

So for now its planning/architecture/strategy -> Opus. Pure coding -> GPT.

Helps with agentic coding that GPT is much roomier with the tokens you get.
