I liked Christy a lot, but I still think that Denee and Eva are slightly more deserving of a nomination. I've said it before and I'll say it again, not everyone can be nominated. If everyone that was doing a great job on Broadway got a Tony nomination, there wouldn't be anything prestigious about it. Last year, Audra Mcdonald wasn't nominated. It didn't mean that she sucked, it just meant that there was someone who was doing some slightly more innovative or more intriguing work. Christy sings and acts her part beautifully, but I think that there are other actresses who are doing some better work out there right now. This part, regardless of a nomination or not, will launch her into a career and I expect to see her nominated or maybe even win in the future.
Also, I agree that Noblezada's Kim has more depth and grit than Salonga's. I know, shoot me.
