When I was doing my research, I read that laser hair removal was better than electrolysis. It was so long ago that I don't remember the specifics. However, that's why I went for laser hair removal for my neck.
The only thing I could think of that would make it better is that it's probably more comfortable and possibly quicker. AFAIK, it's way more expensive, is not guaranteed to work, and there's the possibility of skin damage. My electrolysist has a 2 1/2 page article on the risks/problems of laser hair removal from the Washington Post hanging in her office.
