Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best for teaching a kid to code in 2026.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.
