I’m not sure if electrolyte powder is more hydrating than salt. . .
But I think there’s a lot to be said for making water taste good enough to you that you want to keep drinking it. Often things taste worse than usual when sick and having something you can mix with water that tastes good will make you more likely to keep drinking it. For the same reason I try to have a variety of hydrating things I’m willing to drink around so when one gets old I can switch to a different one.
