If I consume fizzy drinks, both are fine with me. ( i do love
cola)
in fact i find both make no difference.
however Pepsi is sweeter, Coke is more gassy thus for coke, i don't
drink from the can, i prefer to pour it into a glass and let it
settle down. Really cant stand the gas.
I normally got for the light version. and i love to add salt in
it.
