Dune is more profound, but as far as predictability goes, it's almost a one-way street as a book. Which is not to detract that it is very good, and that Stranger in a Strange Land is similar, once the "church" is formed. I found SiaSL as giving interesting insights into what a completely weird alien species might be (much like Asimov's The God Themselves, a personal favourite.) I think that since these two are good, classic books picking one over the other is just a matter of preference, although Dune will be in far more antologies and SiaSL will be more an underdog. Do you have any SciFi recommendation, by the way?
