All these chains are forks of Bytecoin (BCN) (not to mix up with the unfortunate Bitcoin clone also called Bytecoin (BTE). They are written from ground up and stand outside the many Bitcoin based clones by also employing CryptoNote technology, using "Ring Signatures" to anonymize transactions. The POW mining algorythm called "CryptoNight" is also unique and made GPU and ASIC resistant to mine exclusively on CPUs.

Monero (MRO) = Fair launch, no pre or instamine, dedicated dev group of 3-4 core devs still have to come up with substantial improvements over Bytecoin code base, most anonymous crypto solution out there (besides the hyped out Litecoin fork known as DRK which is basically CoinJoin and relies on trust of a few "coin mixers" called Master Nodes), flatter emission schedule then Bytecoin (3 years for the first 50% of QCN will be created), 1 min block time
http://www.monero.cc/Bytecoin (BCN) = Secret launch on deep web (devs stated that Bytecoin was launched 2 years ago) with corresponding premine of 82% of all Bytecoins that will ever be, possibly linked to the mysterious CICADA group (no joke;), first implementation of the cryptonote technology, possibly deliberately slow miner binaries after launch to limit solo miner's success thus further increasing, 2 min block time

https://bytecoin.org/Quazarcoin (QCN) = clone of the MRO code, im not sure if the devs can come up with decent stuff or they will keep forking MRO, irregularities during and before launch (someone supposedly had discovered the devs github repository and began mining before even the dev had started QCn thus increasing difficulty by a large resulting in premine, etc.), emission schedule quite flat (6 years for the first 50% of QCN to be created), 2 min block time
Fantomcoin (FCN) = seems like another fork but at least they are contributing with novelty stuff like merge mining, so if QCN went up FCN will go up for sure. It's on my radar, emission schedule quite flat (6 years for the first 50% of QCN to be created), 1 min block time.
