Kai's verdictA-tier for ops automation. B-tier for simple copy (use Claude).B-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 infrastructure. The one platform every AI dev eventually uses.
