As for the books being hardback vs paperback debate. This set that I am reviewing (the set in this picture ISBN:9781408856789) are indeed the hardback as stated in the listing. I would encourage you just to read the description of what you are ordering and check the ISBN for details.
The art work on the covers of the Red Collection is beautiful. The hardback also has golden inlay stars on the actual cover on all the books as well as golden inlay writing on the Spine.
I got this set in the mail yesterday and stayed up way to late last night reading. :) I am an almost 37 year old adult and I am over the moon in love with the beauty of these books. I actually ordered this hardback set as a Birthday gift to myself from myself. I never read the books growing up but always enjoy the movies and watch them often with my kids. I highly recommend this version set to anyone who appreciates lovely art work on covers.
