I've read both.
I enjoyed reading Origin because I was in awe of how much Darwin could deduce without the benefits of modern science. He formed his theory without the help of genetics or radiometric dating and with a fraction of our current paleontological knowlege. The man surely was genious. The made plenty of notes in the margin tying his statements to the modern science that we know now.
I've read the bible plenty of times. I don't often read it cover to cover but I have read all of it. I think i've probably read the gospels the most, then Paul's letters, then the pentatuech, then the poetic books, then the histories (kings and chronicles) and probably least of all the major and minor prophets.
I have a hard time with the Church's subjugation of the gospels to Paul's letters. I just feel that most Christians make the mistake of becoming more Pauline than Christ-like. I continue to consider myself a Christian because of the teachings of Christ not Paul.
