Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for local inference. If you care about privacy or want to tinker, install this today.
