Kai's verdictA-tier for creators training custom looks. B-tier for general use.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for model-shopping. I use this for every prototype before committing.A-tier for designer-led sites. S-tier if animations matter.
