Generally, is there a consensus on why people use MusicBrainz or Discogs?
Does anyone use both?

I came from using MusicBrainz on another tagging tool.

Somewhere I got the impression that Discogs was best for Electronic and Classical.
(And I don't have much of either.) But this opinion may be out of date or otherwise wrong.

Should I just keep using MB, or should I consider Discogs?
