I recently had the chance to read SQD's When Galaxies Divide and really loved it. I have a spot in my heart for all the good things the NK arc could have brough (but didn't). Still thanks to it we have really epic Elseworld fics like this one, where "Kryptonian" culture gets explored (something that's always a big plus for me) along with the idea of our heroes' relationship against all odds.
I think what I found most brilliant was how SQD managed to change everything around the characters without really changing the familiar feel of the characters. For instance, even though we begin with a different Clark due to his upbringing, she takes us through how he begins to change through his involvement with Lois. I found that part particularly interesting. And I have to say that while some of those chapters were really heartbreaking, I felt a running thread of hope through it all.
All in all, I thought it was really impressive. If you like NK stuff you should take a look.
