I've painted my countertops, but not with the spatter technique. I have spattered a wall, and YES, IT WAS MESSY. Just cover everything well that you don't want spattered. And practice your technique on some cardboard or something first. Make sure you get the effect you want before putting it onto your more permanent surface. As far as the painted countertops, it's worked well for me. I'm just gentle with them and always work on another surface (cutting board, whatever) rather than right on the countertop. Using the nice color gently is much better than living with harvest gold!!!
