Those picks are very weird and probably speculative. I would still prefer to choose monero dash verge xtrabytes and zash over all others as these coins proved themselves over time mostly.
Ya indeed, those picks were the worst.
But Dash doesn't really play along anymore in the privacysphere. Also, they have optional privacy and not on the protocol level. If a person is the only person using privacyfeatures, he sticks out, don't ya think. It's just a bitcoinmixer implemented in the protocol.
Verge actually proved nothing at all. They were supposed to hide IP's, but their wallet doesn't even do that:

Never heard of xtrabytes, but they also have a rich list, which means the blockchain is searchable with your address, so not private at all:
https://blockexplorer.xtrabytes.global/richlistzcash has a set of its own problems (because of the optional privacy which is, as already said, a very bad design choice). Quesnelle did some research, almost noone uses shielded transactions, and when used they can still be linked pretty easily:
