I don't like e-fences either. Where I used to live, I would walk my dogs up this one street that had two black labs on an e-fence. The only problem was that #1, one of the labs was fairly aggressive, and #2 the lady constantly forgot to turn on the fence. They had several incidents where people couldn't get to their cars, houses, etc because the dog would be standing there snarling and barking at them. I'm not sure what happened to the dogs after we left.
