Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-tier for model-shopping. I use this for every prototype before committing.
