Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.S-tier in the agent category. The first one I'd give to a non-technical friend.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.A-tier for data teams. S-tier if you already live in SQL + Python.
