Note: I am in no way the author of this function; I just modified it from another. The original function (_GetIntersection) by BugFix is located here: Compare Arrays, Strings; _GetIntersection Benchmarks: _Diff vs _ArrayDiff vs _Array1PullCommon _ArrayDiff (Author: PsaltyDS, Download Here) _Array1PullCommon (Author: blindwig, Download Here) Note: _Array1PullCommon was edited to return only an array that had unique values from array 2, also the GUI statements were stripped Small vs Big
