Hi and welcome! I've heard that the ones they used at Disney was the Kryolan brand, but this is coming secondhand. I think the sponges and face paint brands are personal preference. I like to use the tack sponges. I bought them early on, because of the price and have now grown accustomed to them and seem to always reach for them over any other sponges I have on hand.
Besides the tack sponges, I've tried the Diamond FX and Wolfe Brothers, Snazaroo's old sponges and their new petal sponges. I've heard that the green (Fardel?) sponge is awesome. I've also heard people swear by cut up car wash sponges. I bought a carwash sponge and it was AWFUL, but since I hear raves, I think I must have bought the wrong kind and have contemplated buying another to see if this is so. Ahhh, the possibilities!
