I have to go with Hansen/ Brody vs Funks. People forget how much of a monster King Kong was...I remember him coming into the old NWA to collect on the bounty on Flair. He was awesome.
I would have to say my favorite at this time (it can change depending on my mood and what matches I recently watched) was Big Van Vader and Inoki in 87/88.
Vader was just unstoppable back then.
