Thank you for this comprehensive comparison!!! I was actually wondering about this myself. It seems there are many ICOs these days that have the same basic idea, though the devil is in the details on which ones are superior.
It depends on what you mean by superior. Why are we using decentralized anonymous markets in the first place? Privacy. Unfortunately none of the coins on the graph offer that. If you check the graph you'll notice none of them use the ring signature method. Why is that? Can they really claim to keep our transactions private?
