I will say PIVX if it goes for an anonymous coin. When I look at the comparison of features between PIVX and other crypto coins. PIVX is a lot better and has all features when all others are missing something. But as we know a lot of this projects is still in early stages and hard developed so there can be new features coming every day.
I like PIVX, it's got a nice quirk to it of trying to achieve everything into one coin. I had some from about $2 but make the mistake of selling the rest of it around $4. Obviously wish I had just kept it all, pretty much like all other privacy coins I invested in and sold too earlier, Verge for example!
When it comes to staking privacy coins however, DeepOnion is in the lead for me. It's still in it's first year so rewards are up to 20%, unlike PIVX where you need a masternode and therefore to invest $50k to get one. I'm coming round to the idea that a decent decentralized privacy coin needs to be a good staker. Not to mention that until PIVX integrates tor (the latest with meek & obfs4) and stealth addresses (which for DO are in beta testing), then DeepOnion will always have my vote. PIVX does manage to encompass all the features of the big privacy coins, but will also be behind DeepOnion as well as ZenCash, even CloakCoin (!) when it comes to development. No doubt in a year's time I'll be talking about some new POS only privacy coin once DeepOnion is a year old
