Edge,
I just replaced all four original shocks on my 84 300D with Bilstein Comforts this past weekend. Man, what a difference. It is really a personal preference as to which you choose. I chose the comfort because I would rather have a softer ride vs. stiffer ride. My brother also has an 83 300D that he put Bilstein comforts on about 6 months ago. I was able to drive his around and get an idea of what the ride is like. If your shocks are shot like mine were, I think you will be happy with either. The ride is so much nicer.
