Kai's verdictS-tier. Category leader. Nothing else is close yet.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.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
