These two books have the same name. Goodreads says the big one contains the small one and the small one is supposed to be volume 1. The beginning of Omnibus looked familiar (I just started reading it). However, the illustrations are not the same as before. The style is different, the table of contents is different, and it just doesn’t look like the same book at all. Looks like a rewrite rather than a combined edition. I’ll post an update once I read the new edition and get a better sense of what’s going on.

I liked the style of the previous one, it was very Dune-like. Hope the new one is also good. My first impression of the Omnibus is that it is heavy, I wish it was an e-book.
