We're all fans of chicken wings here. Buffalo, BBQ, garlic parm, lemon pepper, we all pray under the same church of drums and flats, but there is a common argument that I believe is unnecessary: Ranch vs Blue Cheese.
I postulate that there is not a hard and fast reigning champion for either dressing. Instead, I believe there's a proper way to decide per restaurant.
Every place will have passable ranch. It may not be great, but it will work to serve to cut through the vinegar and spice level of the sauce of the wing. But not every place has a good Blue cheese. Bad ranch is still fine, bad Blue cheese is damn near inedible. So many times ive gone into a bar and their Blue cheese has some crazy vinegar ratio that makes it shelf stable at the cost of flavor. This often has the effect of making it taste quite like puke in my opinion. Strong acidity over rich and creamy with a funky undertone? Thats puke my guy.
All of this to say: Blue cheese is preferred when its good, but when its bad, ranch will always come in clutch. And its okay to want to be safe and stick with ranch.
EDIT: A lot of you are making the very good point that good wings do not require dressing of any kind. To this I say that you are correct. However not all of us live in buffalo (or even a major city with access to a multitude of wing serving places), and wings that need some dressing are better than no wings at all. And in those scenarios, the order of operations is Good Blue Cheese>Good Ranch>Ok Ranch>Bad Ranch>Ok Blue Cheese>Bad Blue Cheese
