Taste, value and the consistency tax
Fast food rankings balance three axes that rarely agree: peak taste, price honesty and consistency across locations. Chick-fil-A and In-N-Out win on operations as much as chicken and burgers — the same order is the same everywhere, which is precisely what Subway lost. Regional loyalty is the chaos factor (Whataburger and In-N-Out fans cannot coexist peacefully), and breakfast is a hidden tiebreaker: McDonald's hash browns quietly hold that entire franchise's tier up.
