Actually it depends on what you are doing.
What I realized I needed to do is use Views that are named for tasks. So, rather than "Artist", "Album", "Panes", I have "Collecting" (View that shows everything, including poor sounding versions, MP3s, etc.), "Family and Friends" (only the best sounding versions, and no avant garde like Ornette Coleman or Bartok), "Exploring" (Panes), "Favorites" and so forth.
Some might use Artist and some might use Album Artist(auto).
Getting back to the OP, I have found the online databases have errors - the most annoying one is when "Artist" is the Big Name On the Cover and "Album Artist" is the actual artist for each track - the exact opposite of the definition of the tags. Unfortunately, neither MC18 nor MP3TAG has a "Swap Tags" function.
