I like fiction better because of the fact that there are no restrictions. In fiction we are not bound by reality and can have anything happen. This is not to say that I don't like non-fiction, but in fiction anything could happen. In a non-fiction story if a person fall of a cliff they are pretty much dead, but in non-fiction a giant flying octopus being ridden bye George Washington could come to save the day as they are being chased by Darth Vader and Godzilla. I must say this option is not likely, but it is more interesting.
