Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier for data teams. S-tier if you already live in SQL + Python.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
