Other. Conecuh sausage.
My “other” choices were a nice salt cured, bone-in, slice of Smithfield/Virginia ham fried crispy with Red Eye Gravy and a local fried liver sausage known as Ring Liver Sausage, generically. I like the looks of all that are listed however, and wouldn’t kick any of them out from under my pancakes or eggs. A few, I have never eaten… One of my other favorites is corned beef hash.
That would be the other poll. 
Nürnberg sausages are supposed to be eaten before 11 am “When they are still fresh”. Still, not necessarily a breakfast item, more like a mid-morning snack. And great with a beer. Also good, as Zeldar’s link mentions, on sauerkraut. We got some once in the wine country along the Rhine with the best sauerkraut I’ve ever had - it was not at all sour, with a nice flavor of cloves and allspice. Went well with a few glasses of wine.
