As for me I don't know any of those projects except monero, and I can't compare monero with them for now. Zcash = $22.80 and Pirate = $0.234 and Monero = $165.76 and finally PRivaCY = $0.009388 and the above prices you can see that Monero is the highest among all. And Monero is more legit then to the others tokens. I have not even heard the others before.

And from the links I provided all the tokens are seeing more promising ones but we don't really trust shitcoins because they can disappear at anytime. And if you like to invest in any of them then I will advise your to invest in Monero and for now I don't trust the rest.
