Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for designer-led sites. S-tier if animations matter.
