Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier in its niche. The only one that actually gets emotion right.A-tier. Best for teaching a kid to code in 2026.
