Kai's verdictS-tier for aesthetics. If you care how it looks more than how it's made, this wins.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.A-tier in its niche. The only one that actually gets emotion right.
