In reality, we often find that in implementation, one or the other are superior, but ideally there should be no difference at all.
Where there is a difference, it is not always in favor of digital transmission either, many digital ins/outs will clip, some are noisy, etc.
I am comfortable with characterizing digital transmission as being generally more likely to be better if there are weaknesses and differences, but it certainly is not in all cases, and in many cases they are the same.
