Didn't know about the big differences in coding style. One more proof. On the contrary to many, I don't believe they are the same person, but I wondered about the same behaviour.
BCNext was a big admirer of Satoshi and tried to emulate him:
I follow Satoshi's vision of the best currency.
Maybe you answered it before... but why the Anonymity? What can go wrong if you'll say who you are?
Maybe it's a superstition but I'm trying to follow in Satoshi's footsteps.
I know there were various of discussions about whether Satoshi Nakamoto, BCNext and Qora are the same person. There are also good proofs (text analysis, on-/offline profiles, etc) which states that they probably could not be the same person.
They also have different programming styles. Satoshi was an old school C++ programmer. BCNext was a Java programmer who didn't follow standard programming conventions (i.e. he put the whole code in a single file with no comments and no of additional libraries). Qora's code was also written in Java but is comparatively well organized and commented.
