Best choice by far.
Glycols (like Engine Ice, etc.) aren't as efficient at cooling. A lower BTU capacity means you have to increase flow rate/volume to get same energy transfer as water.

A look at the MSDS for McCool reveals Hexanoic Acid and 2-Ethyl as primary components.

Alcohol based. So it's functional property is similar to Water Wetter - not as a cooling fluid but as water treatment reducing surface tension and lowering cavitation tendencies near boiling point. Neither provide any anti-freeze properties.
Add Engine Ice or other anti-freeze fluids to your cooling system if you live where there is possibility of temps occuring below 32f. But no glycol-based treatment is going to be as good as plain distilled water at cooling your engine.
