Republic = Corellia, Balmorra, Quesh, Belsavis, etc.
Not to mention the Gauntlet, Voidwolf, Rakton, Emperor and his Children.
Empire = Taris (However, Taris is not strategically insignificant - Excellent planet for poisons and toxins/ Strategic Hyperspace route/ Full control of "Seat of the Empire" region), Makeb, Hutta
Also - Star Cabal, Supreme Chancellor Janarus (Morale Blow, to some extent),
Stalemate - Ilum - Id call this outcome a stalemate...
Yeah, everything in mind, so far id give this to the Republic. Im sure there'll be an Empire Strikes Back kind of comeback, though.
