Convince Me, Verbal: Best Die Hard Film?

It's a question as old as time, and one that has caused more rifts between friends and family than any political leaning ever could. It is of course, 'Which film is the best in the Die Hard franchise?'. We each have a favourite and will attempt to convince the others to our way of thinking, though we are stubborn, we will instead more likely attempt to convince you, which version of McClane reigns supreme.
