The core technology behind Monero, RingCT ensures transactional privacy but not necessarily transactional party anonymity. Alternatives like Zcoin and Zcash employ Zerocoin protocol (zk- SNARK for ZCash which is a modification of the zero knowledge proof) which is great at ensuring anonymity but not necessarily transactional privacy.
VEIL which combines the RingCT technology of Monero and the Zerocoin protocol proves to be the most secure means of transaction currently. It also employs the Dandelion protocol for IP obfuscation at the network layer, ensuring privacy and anonymity at both the blockchain level and network layer.
I think you should have a closer look at it. It may be a gem!
