Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier infrastructure. The one platform every AI dev eventually uses.
