Selects edges using a primitive attribute that have different values for each primitive of the edge.
Edge Wrangle SOP was still 2x faster than this SOP though so there are definitely very good use cases for the Edge Wrangle SOP, even though this SOP uses half edges that should be just as fast.
Edge Wrangle SOP just does some clever shortcuts to get even more performance out of VEX compared to half edges.
