How well do fluids besides water actually hydrate you?

Question

Let’s take for example sugar free Gatorade, or pedialyte. That in itself, is it effective at hydrating you?

Answer 1

Any moderately clear, drinkable liquid is probably 90-95% water anyway, with the exception of high ABV spirits, but those don’t hydrate you well.

So it’s not that “Gatorade hydrates” it’s “water hydrates and Gatorade is mostly water”
