I would prefer 110 volts, so now you are acquainted with two people who would rather be shocked (pain wise) by a 110-120 volt circuit than by a high Joule electric fence charger. The "shocking" thing is that the less painful 110-120 house hold current is much more dangerous than the unexpected "snap" "crackle" and "pop" of an electric fence zapping your average chicken killing predator..
That said after work in my younger days I some what enjoyed the feeling of grabbing an electric fence. I only preformed this feat after Sundown on DRY evenings when I wasn't well grounded. The hired help thought that I was Superman because in the gathering darkness it was impossible to miss the little blue streaks of electronic fire racing out of the leather soles of my work boots and running to ground every time the fence charger cycled. I don't know what color wine goes best with this after work therapy. Try it yourself and post your own personal recommendations. A video would also be fun to watch.
