This is always an interesting debate.
Although darkcoin was not premined, there is clear evidence of an instamine during the beginning. Also the technology that has been the foundation of the coins hype (masternodes) has been inherently flawed. There was talk of implementing cryptonotes "ring signatures" into the project but these coins operate on entirely different algorithms- ring signatures are not merely implemented. I believe satoshi himself would struggle with the task.
The next two coins of interest are
Monero and
Bytecoin although both possessing very questionable emission curves. Instamining in my opinion is unacceptable.
The community answered with the solution of
Quazarcoin. An emission curve that closely mimics bitcoin itself but much smoother (very fair indeed). This coin in my opinion is extremely undervalued.
I do not like to talk about other coins in bitshares postings (unless constructive) but as you asked I will share my knowledge. https://bitcointalk.org/index.php?topic=600658.0Take into consideration both monero and quasar are both in the early stages before the marketing push. As a serious investor- my money is on quasar hedging 10-2 monero.
Community rivalry is strong in the anon sector and FUD/smear campaigns are in full swing. Do the maths and stick to the facts.

PS. I am also eyeing off the ridiculously low AGS at the moment. The greatest investments are made where others have turned a blind eye. AGS are blue chips in crypto.
