I am not locked in to Anthropic, either. I can easily switch between GPT and Gemini models based on how I think each would perform in various scenarios. That's a big win. I use a lot of design with Opus, implement with GPT 5.4.
Also, Github Copilot CLI is pretty much at feature parity (for the stuff that matters) with Claude Code. Using both at work and home, I don't think there's much difference in features between the two. Maybe I'm not a super power user, and just a regular dumb user, but GH doesn't seem buggy and everything I think I'd want to do with CC I can do with GH.
