Don't think they make much of a different. Even water alone works really good..
Straight water is the best for heat transfer. However it's not advisable to use water on it's own as you need the corrosion inhibitors and winter protection too.

NEVER DO THAT

When water is frozen, its volume increases by about 9%. If water were fully filled in a closed space so that there was no room for water to expand, the pressure at -1oc would be about 132 bar. Unfortunately, no engine generally exists to withstand such a pressure. Therefore, a little freezing could cause the engine system to be destroyed if water only were used without addition of anti-freeze. In other words, the engine coolant must contain anti-freeze in order to avoid damage caused by the freezing of the engine and radiator. Since the recent trends of auto industry are to focus on fuel-economy and low-emission engine by using light composite material, engine coolant should also have the following 4 essential functions.
over heating prevention
freezing prevention for engine cooling systems
viboration prevention
corrosion prevention
