Well, here`s my five acres:
Max Endurance is the maximum time you can get in the air. It is not for going anywhere - it is just to keep you airborne.
For example - if you want to hold, for a time or for a long time, you want the fuel to last for as long as possible so you burn just enough to stay airborne. Thats all that is required. It is effecient for minimum fuel over the longest (time) endurance.
Max Range of course, is completely different. Here you actually want to go a distance, at speed, as far as possible. Therefore you fly at the optimum speed where the aircraft flies at its most effecient speed to give you the maximum distance (range) given the weight and altitiude and temperature and least possible drag for the fuel required.
