Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.A-tier in its niche. The only one that actually gets emotion right.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
