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.A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier infrastructure. The one platform every AI dev eventually uses.
