I have to admit my tastes in Scotch Whisky runs the gambit of tastes. A lot of it really does depend on my mood.
At my office, I have a blended scotch that I personally like. I have the Isle of Jura 1984. This seems to go quite well on a Friday afternoon, and actually is a popular choice at our office "samplings".
At home I have close to 30 different bottles. Some I have opened and some I still have sealed. I do agree with the OP that the Port Ellen is a great whisky. I have four bottles of the 1979 at home and love them all. Of course if you read the description in the whisky guidebook, you will get a good laugh.
In the past week I have had the Macallan 18 and 21, Bowmore 12, and a Highland Park single cask (I think it was a 12yr).
On a side note, there appears to be a lot of scotch whisky drinkers on FT.
