Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
