Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.B-tier. Useful for first drafts. v0 is the better bet for shipping code.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.
