I saw all five re-issues in person and am peeved that the original prints weren't use to re-create these album images. Like a Prayer suffered the worst from this because the cover looks blurry and lifeless. I was most excited to get this one since "Like A Prayer" was the first album I purchased (back in 1989). This reissue also clearly didn't have any patchouli splashed on it.
In second place, Like A Virgin doesn't have the same tint as the original cover and is much darker. The image on the back is also no longer flipped upside down but is now right side up which didn't keep with the original album lay-out.
With that said, the best looking re-issues happen to be "True Blue" and "Erotica." Lastly, the "Madonna" album seems to have an improved cover due to the brightening of the image which made it look much better sitting next to the original 1983 issue.
