I think Pugs has the most traditional bar like atmosphere.
The other three have an industrial motif; big high ceilings, a bit loud. At the Dam you practically sit in the brewery at some tables.
Another one to consider is the Blue Spruce Inn in Frisco. They server beer from Pugs and Backcountry. Their menu is upscale for dinner (just ate there last night, yummy). They are under new management and I didn't look at their lunch or bar menu, but they are likely comparable to the rest.
The original four have mid range menus. All good food. If you hit it during lunchtime, I think all have 'working man' lunches. I don't eat or drink out much but I'd go to any of them and enjoy myself.
