Amazing comment @r1s2g3. Let me refer only to cons that you mentioned :)

STO/ICO are not legal in china so still a large market is out of scope.

That's indeed terrible situation, obsession about control of their government has really bad impact on the crypto world.

I guess STO will not be decentralized , so it might not go well with cryto currency enthusiast

Unfortunately yes, STO will never be as decentralized as ICO so it looses part of its benefits. However, I think that this kind of centralization in the crypto world is somehow needed.
