Are Purina electrolytes as good as Save-a-Chick?

[-Bella Cataline-]

I've heard many good things about Save-a-Chick electrolytes, but my local Tractor Supply hasn't had any in stock for several weeks, are the Purina Electrolyte packs just as good?
Any experience/opinions would be very helpful!

Do a comparison of ingredients/analysis. (Google it!)

Probably one is just as good as the other.
