The most important is that it's a bioidentical hormone that can reportedly achieve the same results as these compounds. Which means no liver toxicity and no "unpredictable" negative effects of structurally modified steroids.
Also numerous other benefits like its neurosteroid metabolites, wound healing, bone anabolism etc.
As for the cost we dont really have an estimation right now but i think it will be quite a bit more expensive than primo, at least in the beginning while supply grows. But over time it should get to be a little more expensive than plain DHT as synthesizing it is quite simple. If a vendor like QSC starts carrying it, i assume it wont be exorbitantly expensive like the chemsrc vendor i contacted, and even though it'll probably be more expensive than all DHT derivatives, i think it will be worth trying it.
