Monero is still the most private cryptocurrency, but is slow and has high fees (currently). Zcash uses the most advanced cryptography, but it's privacy tech (zk-SNARKs) is too new to be well peer reviewed. PIVX represents the best pairing of privacy and usability.
Yes i love Monero coin too compared to all privacy coin out there, it stood out that Monero is the best Privacy coin and next to my list is PIVX and Verge which are the most potential coin hope the wraith protocol of verge will release soon.
