Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
