Underdrive Pulley-What's the Diff?

What is the difference in ASP's 25% 850 vs. 950 amp pulley, is it the capability of your alternator? Is it the 15% Alternator pulley worth the extra cost/make a difference?

Underdrive on the Crank, Overdrive on the Altenator. Anyone know a good place to get a nice UD Pulley?
