Kaname; In chapter (42 I think?) She says she'd fall to the deepest depths with him.
Chapter 49 yuuki to kaname: If your sins have caused you to fall from grace, then I want to descend to the bottom with you.
She's been in love with him for ten years now?
Yes, when yuuki woke up as a vampire and drank kaname's blood she said "something must be wrong with me. Whole this time I was in love with my brother."
Zero; She was willing to become a vampire just to help him from falling to a level E vampire.
Shizuka gave yuuki two options:
1. kill kaname and she will save zero
2. if she can't do the first then she should give herself to shizuka and she will save zero
Yuuki chose the second option since she couldn't sacrifice kaname for zero's life.
She gave him her blood to help him over his sinking. (which is a pretty deep love, in my opinion)
In my opion it's love but I see it as family love, not a romantic one.
I know it's not much to go on, but I do indeed believe that Kaname is more loved than Zero.
In my opinion yuuki have a different kind of love for these two men's: romantic love for kaname and siblings love for zero.
During the manga, yuuki stated her love feelings for kaname, but she never voice it for zero.

Probably zero will do what he did in the year which passed: his job as a hunter.
And still being lonely and heartbroken with Yuki's choice choosing Kaname over him? I don't think that Zero would be able to fall in love with any other woman except Yuki.
It wouldn't be a first. yuuki chosing kaname happened before.
And who knows, maybe zero will fall for other girl. the option is still on. for example maria want to catch zero.
I think that Kaname will transform Yuki back into a human in the end; erasing her memories of himself and the Kuran family, and keeping only the memories of Zero and her time with him when she was human.
In chapter 75 kaname said to kaien that he changed his path, aka he doesn't intend to turn yuuki a human, but the goal remain the same, aka building a world where she can live with no fear.
Kaname should also seal her with a spell that prevents her "Vampire self" from devouring her "Human self". I think that would be a good ending
And I'm not bashing Kaname, I just thought I might say how I feel it should end
the one who broke the spell was yuuki, since we suspect that she have the power to break spells.
the vampire self would have devoured yuuki if kaname wouldn't have decide to turn her to the real self and give her his blood. she woke up with no pain.
Suppose that kaname will turn yuuki into a human, exist the possibility for yuuki to break the spell again, but this time, since don't exist a kuran anymore who can provide her blood, yuuki's being will be devoured by the vampire self.
