I can't. As most here have already said, they are completely different animals, and by a wide margin.
Having said that, so many of the characters in Star Trek(all of it) are well developed and multi-dimensional, but I think that is largely due to the casting of numerous Shakespearean actors for lead roles and the volume of screen time the characters get.
The newer SW trilogy suffers from wooden acting and one dimensional characters(not Palpatine), and the reasons for that have been chronicled here before. The OT doesn't suffer from this as much.
Bottom line is I love all kinds of Scifi and these two can't be compared on a 1:1 ratio.
So, what is the point you are trying to prove?
