| Kai's verdict | A-tier. The right answer if you want open-source + terminal-native + model-agnostic. | B-tier. Useful for first drafts. v0 is the better bet for shipping code. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier. Market leader with reason. Start here for serious video. |
