I currently have March U/D pulleys on my 98 GT, what is the difference between U/D and Power pulleys, power wise?

As long as the diameter of the pulleys are the same, the only difference is the finish. For example, it should come as no surprise that MAC pullies are known to dull out and rust after a while. I have close to 100,000 miles on my Auto Specialty pullies and the finish still looks good.
