Kai's verdictA-tier for designer-led sites. S-tier if animations matter.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 in its niche. The only one that actually gets emotion right.
