No reason to start yet another troll war imo. SDC and CN coins have chosen different route than DRK, they rely on hiding the mixing in the blockchain encrypted, whereas DRK removes the mixing from the blockchain altogether. Because we don't know the future (possible math breakthroughs, quantum computers) we can't say with total confidence which approach is better. Both are very likely good enough for the foreseeable future. Some super smart people (like AnonyMint) claim that keeping the anonymity off the chain is the way to go though.
So what we have left that will make a coin stand out (or sit down), is adoption, usability (how well it actually works), PoW vs PoS aspects, other features (like instant transactions), investment opportunities (like masternode rewards and other potential services running on top of them) and lots of other things. One good thing DRK has going for it is that it has had its pumps and dumps and distributions, and is quite mature already. Monero for example is generating so many coins every day that the market can't simply absorb that amount, hence the downtrend. And the young (compared to DRK) PoS coins have the distribution that you would imagine them to have.
Eek, I just looked at SDC's distribution... out of 6,445,964 SDC, 6,130,331 is held by the top 72 addresses. I would assume address 1 is an exchange so excluding that, 83% is held by few. I'll pass.
I would assume the top three addresses are Bittrex, Polo and Cryptsy and that would mean that the distribution is spread to much more than 72 different addresses. Look at the tech being developed at Shadow: Zk, mobile apps, lite wallet, html interface, sdk, decentralized marketplace.. Can you blame anyone for buying up as much as they can? I personally don't see it as a negative. If you're able to see the value in the project's development, then there's nothing negative about picking up a large stake in a promising privacy project. Darkcoin devs saw the value and wanted to pick up the entire stake
If anything it gives the project stability when privacy advocates are supporting the project vs pump and dump groups. Shadow, like DRK, is a long term project that shares similar privacy goals and is just getting started.
Thanks 
Nice
