I have the standard ed., as Lal bought the de-luxe. The only difference (apart from slightly higher quality materials) is that the DL has the cover illustration from the standard as a colour plate inside. There are no 'extras' in the DL. Certainly the DL looks nice alongside the matching DL Hobbit & LotR. I hear Harper Collins are considering a matching Sil DL for the 30th anniversary this year.
