My top 3 picks:

Zcash: Awesome coin with its shielded transactions, which are fully encrypted with zkSNARK algorithm.
Monero: One of the proven privacy coin that exist on the ecosystem for the longest period. Also ASIC resistant.
PRiVCY (PRiV): Its on TOR network. Great community at Discord (https://discordapp.com/invite/4AdxwK7).

Bonus:
Bitcoin Private (BTCP): This coin is as if dead on arrival.
