Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
