Additionally, does anyone have an opinion as to whether ZClassic or ZCoin are better, and, if so, why?
So... you are talking about the Zcrap, Zshit, and Zponzi? Well, let me tell you that they all are the same shit only that with different purposes in order to have more money.
The only good thing of Zclassic is that they are going to fork the coin, so you are going to receive tokens for free, that is the only feature of this one.
Do not put money in there, if the price of any of them goes up, is just for pure speculation
