Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier for designer-led sites. S-tier if animations matter.A-tier. No reason not to use it if you're on Figma. Not worth switching for.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
