I found that the best strings (IMHO) are the Elixier form Gore Tex. They are coated with a special poly-web which makes them last longer, sound brighter, sound louder. They do not rust anymore, less fret noise, etc etc etc
they are a bit expensive, but they are worth it, for they last at least twice as long as normal strings.
