Superconductors are materials that transfer energy with no resistance. Metals are usually the best conductors.
Superconductivity is a phenomenon characterized by zero electrical resistance at below critical temperatures. Metals are the best conductors because the molecules inside them are tightly packed, which allows electricity to travel efficiently.
Water is also a good conductor because of the ions and minerals in it. However, water itself is not a conductor of electricity.
