See, I would say that sausages are way, way underrated. I love them both so much.
I voted sausage but it is a lot more complicated than that. I usually order sausage out, since I can make bacon at home which is more to my liking than the bacon I get out, while sausage out is at least as good as sausage made at home. Also, sausage is for breakfast while bacon is any time. So my real answer is let me have both so I can make up my mind.
I love both and I prefer one over the other in certain dishes, pigs in a blanket ect., so I took the question as, “If you can only have one for the rest of your life which would you choose?” and since I agree with Voyager that bacon is anytime I had to go with bacon.
Let it be noted that this thread has inspired me to hit the market on the way home for the makings of a full fry up: eggs, bacon and sausage, beans, grilled tomatoes and toast. The wife will probably substitute hash browns for the beans in hers. Plus Bloody Marys all around.
No option for Neither.
I like bacon on sandwiches and salads, but couldn’t care less about either for breakfast.
Bacon. I don’t trust sausage, or ground meat of any type.
Bacon.
There can be only one.
Mushrooms? Black pudding? (Doing it English-style requires a banger, as opposed to American-style sausages.)
For me, this is an unanswerable question. It all depends on what the breakfast IS. See the following examples (if I were ordering at a restaurant):
Am I having Biscuits and Gravy? Then I get two biscuits, extra gravy, with four extra sausage links to cut up and mix in.
Am I having French Toast? Then it’s bacon all the way.
Two eggs (sunny side up) with hashbrowns? Four sausage links to cut up and mix in with the eggs and hashbrowns - you must mix the hashbrowns and the fried eggs together, salt it, and mix in the sausage.
Pancakes? Bacon. Definitely bacon.
Scrambled eggs? Bacon, bacon, bacon.
Fruit? I don’t eat fruit for breakfast. Or lunch. Or dinner for that matter. I don’t much like fruit. Except for grapefruit - that’s good. And pineapple. But that’s about it.
ANYWAY - I don’t also eat oatmeal so that doesn’t need to be mentioned in the bacon versus sausage scenario.
Waffles? Bacon. And more bacon.
Finally, for fast food breakfasts, McDonald’s is always a sausage biscuit with cheese or a sausage mcmuffin with cheese (no egg on either) and for Burger King it’s a sausage and cheese croissant (no egg) OR a sausage and bacon croissant (no egg.) Guess the only time I will do either is at Burger King. Which is a shame because the ones that are around here all kinda suck.
Does that answer your question? 
Oh - and I’ll vote in a minute.
I like bacon more and voted for it but when eating breakfast out I more often order sausage because Bacon tastes the same pretty much wherever you get it but some of the places where I eat have particularly good breakfast sausage that I don’t find anywhere else.
No black pudding. Mushrooms are an option, but I can do without so long as I have beans on toast. Bangers are fine, but this weekend it will be Farmer John links.
So it’s an English-ish fry up. 
I like sausage links as long as they’re not too spicy. I don’t much like bacon - too greasy and I don’t really like the flavor.
Bacon. I’m a burner; it’s pretty much required.
I refuse to imbibe PBR, though.
I prefer bacon with “real” breakfast, ie.when I’m eating it before noon. I like breakfast sausage more if I am having Breakfast for dinner.
And for me that is only Breakfast sausage. I love Chorizo, but they are not in the same genus in my mind. Chorizo is part of a dish that requires Chorizo. Sausage is a component of a meal that has wide options.
See, to me bacon is just…bacon. I use it more as an ingredient and usually finely diced than enjoying it on its own in strip form. Sausages, on the other hand, come in nearly infinite varieties. They are awesome.
Hey, if this is an indeterminately-natured poke at me defining eggs, bacon and/or eggs, hash browns and toast as American-style breakfast - sorry, I just don’t know what else to call that meal.
If it isn’t, and chorizo is out, I understand. It’s not usually served on the side by itself. My answer would have to be bacon at that point. If you could burn one end of each slice, that’d be perfect.
This is my answer (which I thought I posted before). Given the choice of only one I’d alternate, unless I haven’t had either for a while and in that case I’d pick bacon.
Hey, quit stereotyping bacon. It comes in a variety of preparations. this variety pack has 5 different styles of bacon, and the same style from different producers can be quite dissimilar in flavor.
TriPolar, I think you posted that in the poll-less thread that got closed.
Depends on my mood. In general I prefer bacon, but for breakfast I often find I’d rather have sausage. Especially if I’m having pancakes or waffles or something else with syrup. Sausage + syrup… mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
If we’re talking strictly breakfast, then I will say sausage (patties for preference) just because that’s almost the only time I would have a chance to eat it. You can add bacon to so many things (salads, sandwiches, hamburgers, side dishes, ice cream) that you would never add sausage to.
On the whole I like bacon better, but I get bacon much more often than I get sausage.
