There are only 2 (TWO) endings - Yes Man and House. Yes Man if you think that Courier is the strongest\smartest\most capable etc. character in the Mojave (so basically you take his "ingame powerlevel" and apply it to the ending).
House if you think that Courier is not a demi-god that can solo entire factions but just a lucky and capable individual. So siding with House will create the most powerful faction in the Mojave.
