Only if you have properly set up one source of every type, i.e., tape, vinyl, CD, SACD, and have used the various media types will you really have the perspective to make this judgement.
At this juncture, my favorites are vinyl and cd and some of that has to do with the proliferation and availability of recordings in those formats. I have some great sounding recordings in each format, but yes, you gotta love those 12" album covers, lyric sheets and posters that some of them came with.
Some day, I just want to tile my rear wall with cool album covers.
