I just don't see the difference using Facing and Fresnel, or Layer Weight as a whole in my node editor.
Is it a big difference using it, is it useful for distant objects?

There are many big differences, among which are that:
- Fresnel depends on the face normals of your mesh - it will not work with inconsistent or incorrect normals;
- The Layer Weight node allows for a smooth blend between the two;
Depending on what you wish to achieve, it may be better to use a specific one, but generally, you'll want to use the Fresnel node, as it's more physically accurate.

$\begingroup$ @stacker Between the two parts of the mask. Both ways generate, basically, a mask to use for controlling mix nodes - black and white - , but layer weight blends the white and the black parts, to give a smoother transition $\endgroup$ Commented Jan 21, 2015 at 22:45
