I can vouch for the combo-infested meta -- ANT/TES and Sneaky Show decks are very common.
GGT doesn't beat said decks.
But that's locally. As a storm combo pilot, I'd rather see an Ancestor's Chosen over FKZ or Sadistic Hypnotist because the latter two are an autoloss.
You can storm enough to kill through a resolved Ancestor's Chosen.
Sadistic Hypnotist rapes your hand 100 percent of the time. Cabal Therapy doesn't always get there.
I'm much more a fan of SH, but that's probably because I'm based in Parcher Dredge.
tldr;
DR targets are strictly a meta-choice. In a perfect world you wouldn't play any. Some days you'll lose the die roll and ANT will get you on turn one. Some days you'll get rocked by
Tundra Wolves equipped with
Bonesplitter.
