As you gave probably gathered by now, 'favourite' is a very subjective term as different versions can be liked for different reasons. There are versions which a generally accepted as the 'definitive version' and it shouldn't be too difficult to ascertain that, but you should also look at these opinions critically. In other words, how was the definitive status bestowed - by consensus, by the opinion of peers such as reviewers, and how long ago - what has happened since then?
Are you going to make a distinction between source and revival?
Another distinction is between variations - there may be more than one collected versions including contemporary alterations.

Anyway, best of luck.
