Would you count supernodes as masternodes? Horizen is a bit different to some of the copy paste masternode coins out there.
Still vote for it, but I think the two tiers of nodes make it a bit different.
Difference between Master nodes and Secure /Super nodes is very great, but for ordinary user it is not important what is under the hood. People like to see some comparisons, an basically principles are the same, you are locking in some final amount of coins and you been rewarded for this..
