I exclusively use Gemini for Chat nowadays, and it's been great mostly. It's fast, it's good, and the app works reliably now. On top of that I got it for free with my Pixel phone.

For development I tend to use Antigravity with Sonnet 4.5, or Gemini Flash if it's about a GUI change in React. The layout and design of Gemini has been superior to Claude models in my opinion, at least at the time. Flash also works significantly faster.

And all of it is essentially free for now. I can even select Opus 4.6 in Antigravity, but I did not yet give it a try.
