Rule of thumb: Never trust that wings from a place that (does not specialize in/isn't known for) wings.
The difference: If they don't specialize in wings, it is likely the the sauce is frozen as opposed to "basted" on.
Further advice: If they don't have a fair range of sauces and flavorings for wings, they aren't a real wing joint.
Most importantly: Even if they fit the two above statements, if wings aren't good enough to make you want to chew the bones clean, they aren't worth your money
