I feel that it is good to go ahead on creating natural links instead of creating site wide links. In recent updates Google has strongly said that it is not a good practice to dump your links site wide, especially in footer. It matter where you are you place your link. Think in this way, you are getting links from home page and in general home will have more URL when compare to other pages. Ideally you link will get less amount of credit.
If you get links from inner pages the link will be natural and it may get more credits when compare to the links from home page.
