For me, the original Star Wars Trilogy hasn't aged; I still very much enjoy the 1977, 1980, 1983 theatrical movies. I have fond memories of all the Kenner figures and vehicles I played with in the early 1980s, and listening to the SW LP again and again.
I can't say how many times I looked at the few pictures of the Millennium Falcon in an old model magazine, admiring its awesomeness and wanting to build a replica (the Kenner toy was functional, but big and bulky) :)
The modern Star Wars I just can't stand. The prequels are offensive. After the "special editions" I lost all respect for Lucas and LFL. The non-anamorphic "bonus" DVDs just sealed my disdain for the modern franchise as it had become.
So for me, there's the "golden age" of SW, from the early '80s to the mid-1990s. After that, I don't want to know.
