Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier for data teams. S-tier if you already live in SQL + Python.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Still early. Manus is more flexible for less money.
