Antigravity is not a windsurf reskin, at least not today; it introduces many concepts and optimisations that you wouldn't find anywhere else, and in my workflows Gemini 3 Flash in Antigravity also happens to outmatch Claude Code with Opus 4.5 on some really gruesomely complicated tasks (i.e. involving compiler/decompiler work.)
They are really cooking with Flash + Antigravity.
The Gemini family seems to be better at high-level, generalizing
The Claude family seems to be better at localized coding tasks
I'm a big fan of Claude Code based prompts with Gemini 3 Flash in my coding agent. I'm unwilling to use any new Google products at this point in time. Used to be a stan, they have pushed me away and I'll never be a stan again
