Ganggreen, It may be the gauge of the wires that can make a difference. On barbed they have 4 and 2 point wires. Then a 15.5, and a 12.5 The high tensile wire, 12.5 can be stretched and poles put much, much further apart than you can for barbed wire. Now that the steel is going out the roof on prices, more poles can take a bite out of the fencing budget.
A high tensile wire is less likely to get damaged since it has more of a spring back if deer get into it or a jumping cow.
We have gone to high tensile 3 strand wire electric fences. We have not had any damage with the deer going over it. There was an old fence that had barbed wire, and if we try stretching it very much it becomes brittle and breaks, and after time, the barbs hang on insulators or staples as you pull, mostly since the poles are much closer together. When we get time, we will eventually replace it all with high tensile. The high tensile is much more maintainance free.
I am learning my lesson on the chargers. Buy a good one and make sure you put lightning arrestors in to keep it from blowing your box.
