Pink vs Blue vs Digital

I see most women on here use pink dye pregnancy tests. Is there a reason you use those and not blue dye or digital testing? Do they tend to be able to tell faster than the others? Or is it just price? I buy digital and yes they are freaking expensive but my thought is that there isn’t any guessing unlike using the pink or blue dye ones. TIA
