My same progression here. I started with ChatGPT website, then Anthropic website, then Cursor, then Windsurf!, then claude, then opencode, then ohmypi, then codex, finally back on Cursor now because I think they cracked the UX for what great dev looks like. The grok 4.5 fast model + cursor ergonomics is insanely good!

The cost of me moving around these different AI models and harnesses was pretty much 0.
