Personally for sound quality I would stick with CD or FLAC format digital file. They are both digital, zero compression and sound great assuming they were mastered properly and you're playing them on good quality speakers. If your speakers are of poor quality or you've lost your high frequency hearing with age, good luck telling the difference.
I can understand the attraction to tape or vinyl formats however. They have a physical aspect which folks also like. It is neat to see a tape load and play or to listen to a record with your amplifier turned off. (The needle actually vibrates loud enough to hear if you listen carefully.) It's like having a steam powered car. It would be fun to play with but not too practical. So just because it's a dated or less than perfect format doesn't mean folks don't have an interest in it.
