Is it more efficient to use the key intersect or the value intersect if both key and value have the same contents for example:

Array
(
    [743] => 743
    [744] => 744
    [745] => 745
    [746] => 746
    [747] => 747
    [748] => 748
)

Is there any difference in performance in using one or the other with the same values. Similar to the difference of using double or single quotes?
