@Everyone, this the explanation. Furthermore, we're talking about shape and pure power. Micro relies more on ingenuity like shaping your attacks but with lesser power and it has more precision. Macro on the other hand is focused on more power than actual versatility.

Like Mugino aka Meltdowner can't shape her attacks and is focused more on destructive force therefore macro. Misaka aka Railgun has more micro because her ability is so versatile but then again she has macro too. 

Accelerator, Dark Matter, and Misaka are the only Espers who have shown to have both shape and pure power. I get this explanation through the novels.
