Thought I'd throw my perspective into the ring:

As an adult child of divorced parents who <i>did</i> make it work - often at the expense of their own feelings and emotions, I can say that no matter how "great" things might work out in the end, divorce still sucks, plain and simple. 

20+ years later, I would say my family is probably a lot happier now than we were before. And I've gotten siblings, extra parents and lots of family as a result. But while we all get along and can occupy space in the same room pleasantly (even willingly), I still don't think divorce is what my parents would have chosen for our family when they first got married.

(Note - I don't think people plan to get divorced; I just think that even though life after divorce worked out for our family, it wasn't fun getting to that place.)
