(I feel compelled to point out that any true lover of sci-fi would never start arbitrarily comparing series and universes to find out which one is better, as that's a disservice to both, but since there hasn't been any STvSW debate anyway, it's not that important)
JJ Abrams is a dangerous case. He needs to have his creative license restricted, because whenever he gets too much freedom, he trashes every project. Lost was great before the dev team trusted him absolutely, look at seasons 1 and 2 versus seasons 5 and 6. Fringe was the same way. If the people green-lighting either franchise get into the mindset of "just let JJ do what he does", then it will take a nosedive. Because that is what JJ does.
