wanting to know what is easier to learn, MOA or MIL?

The notion that there are 2 pi radians in a complete circle has a mathematical grace. That and the fact that the sin(x)/x approaches 1 as x approaches zero (when measuring angles in radians) makes milradians really useful when combined with the metric system, as .1 mil of arc on a 100 meter circle moves the point 1 centimeter. As cool as all that is and as elegant is it becomes for ranging a known sized object using the reticle It is also convenient to keep in mind that .1 mil radian is equal to .343755 MOA. That's really damn close to 1/3 of an MOA. In fact for many applications you can consider a .1 mil click to be equivalent to 1/3 of an MOA and do just fine. It's 6 of one and half a dozen of the other. I have both and do fine with either as long as I remember which scope is which when I am shooting.
