The entire volume was only 21 issues total, but they decided to only collect the Ellis part of it (the last ten issues), and not the Len Kaminski part. If it had collected the entire volume, then maybe check it out to see what 1992 era Marvel was like. But they didn't, so instead it is just unusually expensive for a pretty short volume.
The Satana issue (which I haven't seen because I didn't buy the omnibus) was from an aborted attempt at making rated-M comics aimed at adults (like DC was doing with Vertigo) that came about in 1997. The editors-that-be had ordered multiple books, but then Marvel got sold to new management, and that management demanded that all books be able to be sold in Walmarts. DeMatteis/Sharp's Man-Thing and Paul Jenkins' Werewolf by Night got retooled, but Satana was cancelled completely.
If you happen to be a fan of Peter Gross, some of his earliest work is in the early parts of that volume, and one issue of the Ellis stuff. This was the time period after he finished inking (and later pencilling) William Messner-Loebs' Doctor Fate, and when he started the Books of Magic ongoing title. I personally think that he was trying to follow Leonardo Manco's style on Hellstorm (who was the regular artist for Ellis, and later did a good bit of the art in Carey's Hellblazer) because his Doctor Fate stuff looks closer to his style from Lucifer.
