I have a hard time figuring out which CD packaging I prefer over the other. Digipaks generally offer a premium print that can look better but is more easily damaged and worn. Jewel cases on the other hand are brittle and can become easily damaged as well, plus it can be difficult to remove the included booklet/cover and read it.
My personal favorites are the collectible book style cases with all the extras, though they’re a real pain to store neatly. I actually recycle the jewel cases and keep the artwork with the CD in a nice little case.
