I'm not 100% sure what color the glitter in SU's paper is. (Kind of like how all of the white stickles have slightly different glitter colors, I think the glitter papers sometime vary...)
I like Best Creation's glitter paper a lot-- it's most of my stash.
Here is a link to their white cardstock at Frantic Stamper, which I've always been happy with, but they're in Oregon, so I'm not sure how much faster that will be compared to ordering exactly what you want from SU.
