I’ve been using Claude Pro too ($20/month, same as GG One Pro).
The overall code quality from Opus 4.6 is slightly better than Gemini 3.1 IMO, while its quota is not generous, it’s definitely more usable than the current state we’re experiencing in Antigravity subscriptions.
If Claude Pro is not enough, I’m seriously thinking about upgrading to Max ($100-200/month) rather than paying for Antigravity unless the situation changed.
