I think I much prefer the new version of events where the rebellion actually won and achieved peace for at least a generation before it all started to go tits up again. In the EU, it was just a never ending series of wars, disasters and upheavals. Seriously, I don't think they ever went more than two years without half the galaxy blowing up.
Oh and by far my favourite addition was Mas Amedda's reaction to finding himself in charge of Coruscant. He has no idea what he's supposed to do next and can't get away from it fast enough. I find it much more credible that Sidious constructed an Empire that was incapable of functioning without him than one that would instantly splinter into a dozen little juntas that would take decades to fully dismantle. It's just like a Sith to create a system that encourages all the underlings to focus on eating each other alive, thus preventing them from being a threat to Sidious's throne.
