Computer vs CD/SACD discs

I am simplifying my system and getting out of vinyl. Actually sold all the vinyl and analog gear already. I was planning on going to computer audio and have been playing with it but really don't see the benefit over just slipping a disc into the tray. I also am getting a bit frustrated by all of the options of downloads, cables, inputs and opinions all over the place. I would welcome opinions thoughts on computer audio vs the old fashioned, putting a disc on the tray and pushing play. ( Streaming, I use spotify, exempted as this is a nice way to demo new music).
