Yes, Water Wetter is a surfactant, and works kinda ok to lubricate. Again the soap thing.
Antifreeze is ethylene glycol. IT boils at a higher temperature than water and freezes at a lower temperature than water. Unfortunately, it doesn't transfer heat as well as water, and blocks some of the surfactant effect of WaterWetter, Purple Ice, etc.

Distilled water is water that is boiled, the steam captured, cooled, and collected to give nothing but H2O, all the minerals are left in the boiling pot.
No electrolytes to combine with copper or aluminum.
I use Water Wetter (1 or 2 bottles), water and a quart or so of antifreeze to help with the rust in the A/Sedan car. Dispite what WW says, used as directed, it will not prevent rust! Still hits 220-230 degrees, but better than 240-260 without WW. Plus we aren't really supposed to use antifreeze on the track. Slippery as goose poop! I know.
Not the best thing to do with a street car, because of winter.
You do have to remember to flush the system and fill up with regular 50-50 antifreeze before the 1st frost. (Had a buddy destroy a BRAND new race engine in North Carolina, forgot to swap out and cracked new block).
All that said, for daily driving, extra $10 you don't need to spend. For those that track day, drag race, etc. couldn't hurt and will run 10-15 degrees cooler, even with 50-50 antifreeze. Would work with intercooler, as well.
