Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier for local inference. If you care about privacy or want to tinker, install this today.
