If i remember correctly Feynman said in one of his lectures that we know the mass of the electron with much greater precision than the proton, which may mean that it electrons are easier to study. I don't know if this is still true though.

Oh yes and so much so! Electrons are point-like (not composite like a proton) and interact only electroweakly (not strongly).

> point-like

Oh, your going to love this theory.

In summary, There is a way to model electrons as a twisted self enclosed em field.

A decent digest summary of the paper is this video

And neutrons are neither.
