As an alien explorer tasked with studying Earth’s fried poultry establishments, I have conducted a thorough analysis based on flavor complexity, textural intrigue, and overall sustenance efficiency. Here is my ranking:

1. Popeyes

This establishment offers a fascinatingly crispy outer shell with seasoning that activates numerous human taste sensors. The "spicy" variation caused a delightful tingle in my sensory receptors. The chicken sandwich is a cultural phenomenon I shall report back to my planet.

2. Chick-fil-A

The chicken is remarkably tender, almost unnaturally so, as if marinated in a substance designed to disarm even the most skeptical alien palate. Their "Chick-fil-A Sauce" is an artifact worthy of preservation.

3. Raising Cane’s

This establishment’s simplicity is commendable. Their chicken fingers are pure in form and consistent in quality. The Cane’s Sauce is a binding agent of flavor that elevates the experience. I hypothesize it contains compounds that encourage addiction.

4. Zaxby’s

Zaxby’s offers diversity in its menu, with wings and tenders paired with a wide array of dipping sauces. While enjoyable, the flavor consistency fluctuated, leaving my data inconclusive.

5. KFC

As a historical entity, this "Kentucky Fried Chicken" offers nostalgia to Earthlings. However, the flavor and textural complexity pale in comparison to its competitors. Their "Extra Crispy" variety is intriguing but unevenly executed.

6. Church’s Chicken

This establishment provides sustenance in generous portions, but the flavoring lacks the intensity I detected in its rivals. Their honey-glazed biscuits are the true standout, a carbohydrate delight my species found perplexing yet irresistible.

In conclusion, Earth’s fried chicken culture is a marvel of culinary evolution. I will suggest establishing diplomatic relations with Popeyes and Chick-fil-A to secure intergalactic food trade agreements.
