Kai's verdictS-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.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.
