Based on 991 opinions on Hacker News from developers who discussed these two, most of them first-hand users.
OpenCode comes out ahead on nearly every measure. It has 780 opinions from 569 authors and 66 approval, against 211 opinions and 29 approval for Gemini CLI. Its aspect counts favor cost/pricing (113 positive to 24 negative), customization (83 to 8) and UX (95 to 47), while Gemini CLI's reliability reads 7 positive to 55 negative. OpenCode's own reliability is its weak spot at 39 positive to 83 negative, and its 90-day approval of 55 trails its lifetime 66, so Gemini CLI is the better pick mainly for someone already inside Google's stack who needs a low-cost fallback.
