I think good packaging is harder to judge. In theory, you could wrap a bottle of whisky in an Edvard Munch original and call it packaging. The question is where to draw the line. Personally, I would draw it at a bottle, label, tube or cardboard box. Once you get into the realms of wooden boxes, glass cases, display stands and start giving away other little gifts - decanters, maps, certificates and the like - I think you are talking about something more than just the basic presentation of whisky.
So, within my own self imposed rules, I think the following brands are outstanding:
Bunnahabhain old style - especially the limited bottlings
Highland Park old style
Isle of Jura
Littlemill dumpy bottles
