A few years back, I essentially wrote a novel in a text-based RP forum. My primary coauthor deleted the forum in a fit of being a teenager. I had, on my computer, a few reference documents ("Threads by Date," which showed the characters, locations, and titles) and a few excerpts. In addition, I had a copy of the last chapter, considered by all who have read it to be stunning; most of them cried despite themselves when reading it.
Due to the number of hours I invested, my attachment to the work, and the powerful nature of both story and finale, I have long talked of a rewrite. However, as I did not originally know this was to be a novel, there is, technically, no beginning. After much research online as to what sort of elements were required for a proper opening sentence, and several hours of trying, I managed only two that I cared for.
My former coauthor strongly preferred one; my roommate the other. Both are people who know me well and whom I respect, among the only I'd bother to ask or who would bother to answer. However, my coauthor commented "but perhaps that's because I know the story." My roommate, ironically, said, "but I don't know all of the story."
So, since none of you know . . . which is better?
