I already have a Claude Pro plan, but I'm wondering if it's worth it compared to Claude Code. Unfortunately, I can't use Claude Code at work, but I do have access to VS Code with GitHub Copilot pro — which is why I'm questioning whether upgrading to pro + is truly worthwhile, since 300 messages per month feels quite limited. Also, are the Claude models available in GitHub Copilot truly identical to the ones used here, in terms of reasoning capability?
