Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.	A-tier in its niche. The only one that actually gets emotion right.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
