In my experience, Sora was fantastic for what it did. Light years better than Adobe Firefly. On par with Leonardo.

A lot of YouTube content is really talk, so it was easy to create Sora videos as video content while you talked over them.

However, its failure was that it watermarked everything. WTF? Leonardo didn't do that. Neither did other models. So while video gen was excellent, you always had these ridiculous floating watermarks.
