My ranking is as follows:
1- Squall: I really identify with him, we are both lone wolfs, he uses a gun sword, the first of its type (second is Lightning's, which I also love and identify with). Although, he dislikes confrontation, he's in your face and will tell you what he thinks. Lastly, I liked his style and his necklace. Plus, Griever for a pet name sounds really cool
2/3- Zell and Rinoa, I sort of pair them up because there are things I love about them, but I can't really decide which comes first. I like Zell's energy and idiocy, plus he's got a cool tattoo. As my friends know, and as I usally say: I don't do blondes, but I would definitely do Zell. Rinoa, on the other hand, is the one that comes into the story with a really cool dress, a really cool weapon and a really cool dog and who ultimately is able to penetrate the heart of the lone wolf. So, I sort of saw her as kind of ray of light for Squall.
4- Quistis, her whip kicks ass. She is also in your face, which is a quality I enjoy about people, although she ultimately fails to be in your face once Squalls rejects her. The way that she is not able to handle the rejection properly and how she spends the rest of the story brooding in the background was what ultimately made her drop from potential first spot on this list.
5- I was almost going to pair the last two of them up as joint last, but Selphie has the love of trains going for her and plus her weapon is really cool and she rocks in the school girl outfit.
6- Irvine is just too sad to comment....
