Kai's verdictA-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for designers. The only one that takes vectors seriously.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
