After the recent crazy bull run of darkcoin, the two coins sitting on number 4 and 5 on coinmarketcap both offer their own version of anonymous transactions to cater to those who want privacy. Darkcoin uses coinjoin with its darksend feature, and bitshares uses stealth transactions with TITAN (transfer invisibly to any name).

As I understand it coinjoin is basically every time you send a transaction, the transaction is mixed together with other people who are sending transactions. Stealth transactions means that every time you send to an address, you actually generate a new public key for the receiver so addresses are never reused.

What are the pros and cons of each kind of anonymous transaction, and which one is better overall?
