From a (my) marketing perspective.
BitcoinDark = Bad name. Just as bad as Darkcoin.
Darkcoin's Darksend = Centralized masternodes, not good at all.
Bitshares TITAN = Could catch on in the future, but the whole system is in a testing phase. However I really like Bitshares, the idea and what Daniel and his team is trying to create.
Monero = The best name, good distribution of coins to a lot of holders and many small players. Very good anonymous features. Many developers and cryptographers love it. I personally love the name and the fact that is anonymous.
