I've tried a number of different white inks, including most of the ones mentioned here, and was never satisfied with the results. The one I've been happiest with is the Hero Hues Snow. It's actually a chalk ink. Another crafting friend of mine, who has tried almost everything available, has also become a fan of this ink. I own three other whites that I use only for embossing.
Keep in mind that your results, with any ink, will always depend in part on the paper you're using. Some papers absorb more ink.
I'd like to try the Brilliance, since I like their inks, but in the meantime the Hero Hues remains my go-to white ink.
