Kai's verdictS-tier for speed. When latency is the product, start here.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
