Speaking of dips, when it comes to potato chips, the only flavor I tend to actually dip is original/regular, because they generally have no flavor - the dip adds some flavor to them. Otherwise, this is why I usually go for flavored potato chips like sour cream and onion or barbecue.
Similarly, when it comes to plain tortilla chips, I'll dip them in salsa or queso, but I usually prefer queso over salsa.
