I'm also mostly on Gemini 3 Flash. Not because I've compared them all and I found it the best bar none, but because it fulfills my needs and then some, and Google has a surprisingly little noted family plan for it. Unlike OpenAI, unlike Anthropic. IIRC it's something like 5 shared Gemini Pro subs for the price of 1. Even being just a couple sharing it, it's a fantastic deal. My wife uses it during studies, I professionally with coding and I've never run into limits.
