As much as I was angry at Zuko at the end of Season 2 for his choice, he wouldn't have matured nearly as much if he hadn't gone back to his family and been smacked in the face with everything he'd been trying so hard to ignore. ♥ him, really.

I thought Aang would have been far better off with Toph. But I didn't ship Katara with Zuko, either; I liked Mai, and thought Katara needed more self-identity, too. But she was interesting to explore.
