Except that filler shrinks as it dries. If you're going to tile afterwards, then bondings fine. If you're going to paint or paper, then try Gypsum one coat plaster.
Yes, it's basically bonding and plaster all in one. You won't get as smooth a finish as you would with multi finish, but if it's being covered afterwards its fine, and for filling round back boxes, it's great, just not that cheap. You can get it from Wickes.
