Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
