I have board and post with wire electric fence if needed on the inside, two strands, one top and one bottom. It has been up over 20 years now and this summer I had to have a bunch of the post replaced as they were rotted and leaning and everynow and then they break a board either trying to get at grass growing along the edge or someone decides to rub their big butt on it. I really only but the electric fence on when a new horse comes in or in the spring when they want that grass. The only pain about it for me is that both paddocks are surrounded by woods and all the growth during the summer grounds out the wire as it grows like wildfire and I just can't keep up with keeping it cut back. Otherwise I am very happy with it. I have known many that have done the tape and it just does not seem to last but is good for a quick solution until you decide which it is you prefer. Board and post is expensive to do all at once but last a very long time and then there is the updated maintanence like I said. Also some horses will never cross anything and some will. I need to know that they are not going anywhere! Good Luck it whatever you decide to do.
