Hmm...I'd argue that Cyberpunk and SciFi are one in the same. The science fiction writer, William Gibson, coined the word cyberspace and his stuff is science fiction. Science fiction is my favorite, especially traditional space stuff. My first book was Starship Troopers by Andre Norton. My favorite today is C.J. Cherryh. Fantasy is a close second. Andre Norton again and of course Tolkien. Jules Verne is actually steam punk now that I think about it. Not a fan of alternative history, since I have a degree in history.
