    One has potassium and the other has sodium! They are both salts of benzoic acid.

    But really, the two are the same in terms of their functionality -- they are both the conjugate base of benzoic acid. If you are simply making a buffer solution with benzoic acid and a benzoate salt, it makes no difference. However, if being used for human consumption, there is a difference between potassium and sodium.
