Based on 249 opinions on Hacker News from developers who discussed these two, most of them first-hand users.
Neither tool wins a head-to-head here: no commenter picked one over the other. Kiro shows 59% approval against 29% for Gemini CLI, but that rests on 38 opinions from 30 authors, while Gemini CLI has 211 opinions from 175 authors.
