You go through these list with a broad coverage and if an artist really really take your fantasy, you then explore further within their output.
So you get a broad understanding while at the same time explore deeper towards artist and then genre you like.
For example I get a broad overview going through George Starostin anthology. I then dig deeper within the band discography such as Genesis where I end up listening to their entire career. Then I going deeper to various other prog group where I listen to their entire discography of for example King Crimson and Yes. Then I dig deeper by adding the Prog Archive Top 100 album list in my rotation.
So you have a broad opener list that gives a good overview. Then you go deeper within subgenre that you like
