Well, against the (now somewhat uncommon) TR leads, I usually bring Cresselia along to shut TR off, so it can do a bit of SE damage with Psyshock, albeit with less power and surprise value. Not concerned about Scrafty in this respect, since I've only seen him in a TR lead once since VGC11.
...I just wanted to know which gem would be optimal in most cases.
