It's surprisingly simple to switch. I mean both products offer basically identical coding CLI experiences. Personally I've been paying for Claude max $100, and ChatGPT $20, and then just using ChatGPT to fill in the gaps. Specifically I like it for code review and when Claude is down.

Try GPT-5.5 as your daily driver for a bit. It felt a lot smarter, reliable, and I was much more productive with it.
