Kai's verdictS-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
