Even though of course we would never find ourselves in most of these characters' situations (i.e. the mechs, wars, girls, etc etc), their behavior and philosophies still apply to our world.
So mine would have to be Belldandy. She always tries her hardest to solve problems with a favorable end. She never complains, never lies, and especially doesn't flash herself like her other other anime series cousins. And a plus to that, she's absolutely gorgeous.
If I had to pick a male character as well I would pick Hibiki Tokai. He's a real pain in the ass in the beginning, but as he grows he learns the most important thing in life: friends. His story and role in Vandread is something we all should follow. But still no one comes close to Belldandy.
So there...
