Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for designers. The only one that takes vectors seriously.
