Right, until the ice melts. And that's why you use salt when making homemade
ice cream: to enable you to have icewater at a temperature lower than zero C.

An Ice/water mixture at 32deg F is probably better than just ICE alone
at 32 deg F.

But..

Ice alone could be at -20 deg F or any other colder temperature.

Then the answer is not so obvious...

Ice/water at 32 or ice at -20?
