I'm not yet invested in either coin but I've been following both and Filecoin hasn't been released publicly yet since they finished the ICO. It's unclear if the Filecoin being sold on the Gate.io and LBank exchanges is genuine or not as Filecoin recently tweeted that anyone claiming to be selling their coin at this time is most likely fraudulent. I believe that being first out of the gate for a particular idea gives you a certain advantage for sure but time will tell what will happen once some of these ideas mature and they can be compared directly. STORJ looks nice too. Lots of options for storage coins.
