Should I get another Siberian Husky or a Border Collie?

We have a 6 month old Siberian Husky currently and he's wonderful. He's good with children and even our ferret(they play together) and we're thinking of adding another dog as a playmate.We know this will probably mean twice the work but that's okay. I've grown up with Border Collies on a farm so I know them well and know they need ALOT of exercise. Im just wondering if they would work with a Siberian or if its better to get another Sibe for our boy. Also does anyone know how Collies are with snow? Never lived in a snowy area with one before.
