I've found that Elixir strings are by far the best brand I've ever played. They have some patented gore-tex coating that almost eliminates all squeaks and makes for a much smoother and cleaner feel. The only thing I have against them is that after a lot of play the coating can peel away. Anyways, after playing them I've never gone back to conventional strings. They are a bit pricey, my set of lights cost me 18.00 Canadian. I have only ever bought them for my acoustic, but I would imagine that they make them for electric guitars also.
