I'm another who preferes Jillian (I seriously want one of thsoe jackets!!), but thinks that Christian will win. I personally thought his collection was overly similar, for my taste. He's super-talented, but needs some maturing.
I actually think all three have some really stunning pieces (Jillian's jackets, Rami's gowns, Christian's first ruffle skirt and some of his tops), so I won't be upset, regardless of who wins. I also think all three have great potential to be future superstars.
