I did a review of all of them recently (OK, there are way too many to review all...but, all the official and semi-official ones), and my favorites were Reasonix and MiMo Code, partly because they're the least like Claude Code, while everyone else is a mostly direct copy. Reasonix is not great on all fronts, but it shows how much money you've spent at all times, it's fast, it's not a direct copy of Claude Code, and it is designed specifically to maximize DeepSeek caching, so it's free real estate...like a buck a day to use DeepSeek models hard. MiMo Code is just cute as hell. It's got (mostly tasteful) animations and emojis and such, it's fun to use. It also is not a direct copy of Claude Code. It almost feels like a GUI app. MiMo Pro is an underappreciated model, too, at least for some classes of problem. It's very good at security vulnerability research, and very cheap. It's slower than DeepSeek and more easily confused by tools, but it's uncannily good at reading code and identifying security bugs (rough parity with Opus 4.8/GPT 5.5 at more than an order of magnitude lower price); and with fewer false positives than most models, including the frontiers. And, to keep it on topic, Antigravity refuses security work of any sort, so it's unfit for purpose. Gemini 3.6 Flash is pretty good at security work via the API, so it's not the model rejecting, it's the agent, which is extra annoying.
