Faction Ideals and Philosophy

So with the end of the alpha, let's look back on the glimpses we got at three of the factions that were exhibited. Dead Orbit, Future War Cult, and New Monarchy. Three different factions with three different endgames. New Monarchy seems self explanatory, Future War Cult seems to be preparing for future wars (see what I did there?), while Dead Orbit seems to be under the impression that the Traveler will never awaken, and that all should flee before the Darkness returns. Which ones sparked your fancy, and which ones did you turn the other cheek for? I personally did not like Dead Orbit, but New Monarchy seemed the most optimistic about the future, and I am curious about the others that have not been identified, like Osiris and the Seven Seraphs. I want to hear your thoughts on the matter.
