Ludwig's WRAP-UP
In summary, the phrase "either of the" is a versatile and grammatically correct way to introduce a selection between two options.

Popular sources such as The Guardian, The New York Times, and BBC frequently employ the term, further attesting to its reliability and appropriateness.
