Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for content creators.
