Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier. Best for teaching a kid to code in 2026.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
