Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
