If you have a Parent style and you have a footer template in it, then you have a Child style that is a child of the Parent..... if you do not edit the footer template in the Child style, then it will use the footer template from the Parent style. However, if you edit the footer in the Child style, then any edits you do to the footer in the Parent style will not get magically merged into the Child style footer template (thus, the Child style modified footer template is independent of the Parent style footer template).
As for the better performance, it's hard to say since we know nothing about your site or server or anything. If it were me, I'd go the easy route of using Replacement Variables and if the server loads are fine, then go with it until sometime in the future when the server loads are no longer fine.
