Shouldn't find any other differences in terms of cooling.

Not true I'm afraid. Coolant does two things to water. It lowers the freezing point and raises the boiling point. Thus at the freezing point of water, the coolant is still fluid, as it is at the boiling point of water and therefore with just water in the system, the temperature will rise significantly quicker.
With a 50-50 mixture of water and antifreeze, the coolant's boiling point can be raised to around 130°C
You wouldn't want to get caught in traffic on a hot day with just water in your rad...
