I think that fidelity is the only important measure in media because it is what lets the author give the purist possible reproduction of their work to the consumer. All media has a level of degredation between thoughts, words, and interpretations, but digital is the one that has the highest fidelity.

Further, if the author intends, they can take their digital and make a vinyl; or record to vinyl, distribute as digital. (caveat: potentially having a double-lossy situation) Once you have a lossless digital you can publish it over two cans and string if you want. So it is quite literally a superset of analog media.
