What does he have to gain from her? Back in the Post-Crisis era, I think it was clear that she was more decisive than he was, which was a major issue that built up to all those Crises in the middle of the decade. If that type of characterization were to carry over now, and to some extent I feel it does, we would see that WW would be more likely to decide expediently what's right and wrong, act on it, and deal with the consequences, whereas the back end of Post-Crisis Superman was often caught in paralysis by analysis, not knowing what the right thing to do was, and being afraid of bad outcomes. That's why we got stories like "Grounded," or that infamous Batman line about the last time he inspired anyone was when he died. I think this is where Tomasi was trying to go, but it had very mixed results.
If you followed the Morrison model, though, that's not something Superman would gain, because Morrison's Supes is always a step ahead. He's prepared to be quick to recognize and analyze a situation, so he doesn't need Batman or Wonder Woman or whomever to tell him to act. So what should he get? I think it should be something similar to what she gets from him: merely another person's point of view of the world, and not to mention companionship.
Honestly, though, asking the question of what do the characters gain, other than companionship, would be the wrong way to write them. Granted, no two people are exactly the same, and you and your friends/partners/relatives/whoever will be better at some things than the other, and the other will be better in other things than you, and given enough time together your good and bad habits will probably diffuse into one another. However, that's likely not the primary goal in forming bonds with other people. I think when you look back in Superman's past, a lot of people liked to ask what does he see in Lois, or what does he gain, and the only answer that really mattered was does being with her make him happy. I never had a need for their relationship to be justified any further than that. Perhaps people think that kind of writing is kind of bland, but I'll take its realism over melodrama.
Anyway, that's probably why I like buddy films and hate rom-coms.
