We have a combination of board and horsecote/hotcote wire. The board is about to be painted black and is on the stretch facing the house on the pasture as well as the small turnout/sacrifice pen by the barn. The wire is hotcote top, middle and bottom and horsecote on the two remaining strands. Right now we are saving towards fencing another portion of the property so we can use rotational grazing - the area we have right now is right on the edge of not being quite enough. In retrospect, I wish we had done 4 board rather than 3, we may fix that when we do the next bit.
Gee, everybody but me has NICE fences. Ours are OK. Namely barb wire. It's what was here, and I don't own the place. Had to put up some extra fence it's it's got smooth wire, plus the top one on MY fence can be electrified. But it's mostly woody enough we don't have to worry about them trying to go anywhere.
