Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier in its niche. The only one that actually gets emotion right.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
