Hubbell is a superior product to Leviton IMHO. I much prefer receptacles that have the face dished around the slots vs flat faced, it makes it much easier to get a plug in, especially when you're reaching down behind a sofa or cabinet or something to do it. Is it worth 3x the cost? That I don't know, I usually buy the spec grade Pass & Seymour Legrand receptacles, they're $2.79 at the local hardware store, very well made and have the same dished face.
