Digi vs Dye tests???

Courtney
Soooo... I've read that pink dye tests are more accurate than a blue dye test? (Is Wondfo a pink dye test?)
But which is more accurate...a pink dye test or a Digital??
Does the Digi really require more hormones to show a positive?
Just trying to figure out what I want to use :)
Best of luck to all!!
