I prefer the second pictures with just the ship. Options 1 & 3 are just blah! (Actually, Option 1 looks like they just recycled the booklets that were in the DVD's that said which episodes were on which discs.)
Plus, how many times do people look at the artwork? Sure, on the store shelf, but really when you get home, do you really notice the artwork, or are you more interested in what is on the discs?
