Good call @calicrypto.
I might add a table at the top of each of our coin reviews showing this type of information.
Very difficult to say which is better Zcash or Dash. Zcash has zk-STARKs to hide addresses and transaction amounts and Dash has the "privatesend" option. Neither of which has been broken, security-wise.
I should also mention Verge - which hides your IP and network packets using TOR and I2P.
