I will preface this by saying I have not read either, but I have read about them a lot. The original Nightworld was the end of the 6 book adversary cycle consisting of The Keep, The Tomb, The Touch, Reborn, Reprisal, and Nightworld. Jack appears in The Tomb, but at that point in time there were no plans for the RJ series so the Jack in the original Nightworld knows little about the secret history of the world and the Otherness. The RJ series happens before Nightworld, which now ends both the AC and RJ series. The Jack we have now knows so much more than the Jack in The Tomb, so the revised version makes more sense with the character now.
I have been patiently waiting to read Nightworld after The Dark At the End. I also plan on reading the original after for comparison. If you are looking for more to read, I would suggest the AC books mentioned above, Black Wind (a favorite of many on the board), and the 3 short story collections as some of the short stories also tie in.
There are people here that have already read both versions, so they will be able to post from the point of view of someone with that knowledge. Welcome to the board!
