Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
