There are a few problems with your proposition:
-Are we comparing two universes? Because then you run into opinion based arguments, which are pretty much useless for comparing two things.
-Are you asking which IP wins in profitability? In which case, are you only counting the movies? What about non-canon novels? Are you adjusting for inflation?
-If you're asking whose spaceships would win in a fight, there are a ton of questions that need answering. Which movie are we taking the technological basis from? Are we talking into account The Old Republic? What about the books after Episode VI? Are you making the supposition that the Rebels and the Empire might join forces out of a common foe, or are they also still fighting each other? Do the different factions from Sins join forces for that matter? Do pirate raids come into play?
These are the things that need to be straightened out before we declare a winner.
