Kai's verdictA-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
