There's nothing really logical about the desire to own NFTs or physical animation cels, so I'm not going to claim one is better than the other in some objective way. But, to put it extremely mildly, those two things scratch entirely different itches. I guess if you don't care about either of them, then they might seem superficially similar. However I don't think anybody interested in one of those things would consider the other one to be remotely similar. NFTs are about proving you own something. "This is 'mine', and nobody else can 'own' it, until I sell it." Owning a physical animation cel is about touching a piece of history; a physical artifact of a near-magical process. It's like holding one of Michaelangelo's paintbrushes, versus looking at a picture of one of Michaelangelo's paintbrushes. Again, nothing logical about one or the other, but we are not robots.
