Limit Switches

I am adding limit switches to my Sphinx CNC router. Question. Should I set them up to home to max, or home to min? Does one have a benefit over the other, or is it just a matter of personal preference? I will be making them normally closed as well.

Personal opinion, home to the most out of the way area. I home to back right (Xmax, YMax) and Z of course up at the top.
