Kai's verdictB-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.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
