Kai's verdictS-tier for speed. When latency is the product, start here.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for solo + free. The best free option, hands down.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
