Like many others I current have at both Sam's and Costco. The brisket packers at the 3 closest Sam's are always select. While the Costco has always had choice packers and they are the same price that Sam's is selling the Select packers for. I prefer the ribs at Costco as well. Now just like others have pointed out Sam's does have the bone in pork shoulder.
As far as the friendliness cleanliness I think that is more to do with the demographics of the area unless you are lucky enough to have a Sam's and Costco directly across the street from one another. At which point the CostCo does prove to be better IMO.
If I had to only chose one membership to keep I would keep Costco.
