dporn.club is already launched for one lol. It's different simply because they have a different idea for their platform. It looks like it will mostly be OK with more spammy NSFW posts although perhaps over time they will see the value in original NSFW creators and it will evolve to be similar to dporn.co in that regard.
It also doesn't have the whole pre invest currency going.
I also don't know if they plan to add streaming [dporn.co wants to have streaming capabilities as well as video posting]
Theres a bunch of other stuff but ya it will really come down to preference I assume =)
