Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Still early. Manus is more flexible for less money.
