as far as boxed sets go, I believe 2001-2005 was by far superior to all other years except 2008 because of the aspect of building a set that actually functions to do something cool instead of just looking cool. however, 2006-2010 beat the earlier years in the area of canned sets, in that the newer sets were far more articulate and fun to display due to the fact that they were just more fluid than say, the Toa Mata. I have no regrets about set design but that's just the way I view the sets in general.
