The correct phrasing is "you're one of my favorite people." The word "person" is a singular noun, so when referring to more than one person, the plural form "people" is used [1].
Using the phrase "you're one of my favorite persons" is grammatically incorrect because "persons" is not commonly used in this context. While "persons" is a valid plural form of "person," it is typically used in legal or formal contexts, such as when referring to a specific number of individuals [1].
To express that someone is one of your favorite individuals, it is more natural to use the plural form "people." This acknowledges that there are multiple individuals who hold this position in your personal ranking [1].
In summary, the correct phrasing is "you're one of my favorite people" when referring to someone as one of your favorite individuals.
