With 2016 diesel technology, the only "less-emitting vehicles" are EVs and possibly CNG-powered vehicles. As for cheating, as long as the manufacturer does its job (by either eliminating EGR altogether or installing a catch can in the PCV system), there is little to no incentive to cheat on the operator's part. Urea is dirt cheap as long as you don't buy from the dealership.
I was comparing modern diesels to older ones, was that unclear? It's not difficult to get enough 2016 diesels in an area small enough to violate the short-term standard for particulates. And I'd bet your confidence about cheating is misplaced; time will tell.
