There are similarities but Fire is more of a space opera and Deepness is more of a character drama. The tech details in Fire are more fantastical since they involve superluminal communications/travel and the book centers around the mechanism that makes that possible. I like Fire more because I like the pacing and the xenos better (space operas are fun) but the tech and its implications are far better in Deepness. I like the depiction of computing/programming in both and both have the history of technology as a major theme, which is one of my favorite topics.
