UGC ads. Not talking-head avatars.
HeyGen excels at corporate explainers, training videos, and presenter content — third-party reviewers describe its scope as "limited to talking-head presenter videos and explainers." That's a different category from consumer UGC ads, where the actor holds the product, eats it, wears it, demonstrates it. U-Gen is built for that second category: five interaction modes (hold, wear, taste, surface, touch), product URL import, ad-tested output formats.
Two different jobs. Pick the tool built for yours.
