Luckily my ship is canon, I cinta Harry and Ginny together. They understand each other perfectly, they're both passionate and even share the same sense of dry humor (and cinta for Quidditch :P). Even Rowling berkata that they are soul mates.
Edit: Now that I think about it, I also like Harry and Draco together, I'm a sucker for love-hate relationships and since Harry and Draco are kind of two different sides of a coin, I think it would be very interesting. Plus, I'm 90% sure that Draco had a crush on Harry, he was obsessing over him way too much.
