there are only 2 privacy coins in there: monero and sumokoin, all the others have rich lists, so not private/anonymous:

Since sumokoin is just a cheap clone of monero with a huge premine (which is a big nono for anonimity because one entity has a lot of the outputs) and no devteam there's only one right answer really... MONERO
I ve already answered about XSPEC in another thread and will repeat myself for any newcomers passing by:
XSPEC's professional 15+ years cryptographers are preparing default stealth addresses and first ever in crypto staking on stealth addresses in Q2 2018.
Technical document will follow ofc.
By then stealth addresses will become the default ones and with stealth staking there will be no reason to go on public addresses again.
Besides that XSPEC already features an impressive list of tech, because of which without any shiny website, comprehensively written whitepaper or paid marketing (simply no funds for that right now) made almost x10 in one month:
- One of the best clients with fast transactions speed 30-60 sec txn's
- Integrated natively in-clinet TOR + masking TOR traffic mechanism (OBFS4) - helps to get though gov firewalls and provider monitoring
- Stealth Addresses which is a big deal if you know what they are for
- Automatically Adjusted in size Ring Signatures (screws blockchain analyzers)
So you can that it is almost makes it a Monero on PoS. A rather good compliment nowadays. We're waiting for defeault stealth addresses
