I send my dct's to sophiatx. By the way, I didn't hear dct before sophiatx but after I use it I can say that it is damn fast. It is going through in 5 seconds.
Maybe that is because not many people use the network? Anyways, it is good promotion for DCT that SophiaTX is giving 10% bonus for DCT payments
Etherium was also very fast a few weeks ago but with this exponential growth of transactions, it's very congested. Let's hope vitalik does his best to speed it up.
