Msd vs. HEI distributors

Would an MAD 8388 ready to run distributor be any advantage over an HEI converted factory electronic distributor? This will be for my bone stock 87 ramcharger. I have a brand new mad sitting there for another motor. I've been running the HEI now for 4 years with no problems. Curious if it would get me any better milage over the HEI.
