None of the open source solutions like Hashtopussy are genuinely supported, I don't see winxp5421 and s3in!c selling support packages or giving out a 1-800 customer support number. Also, open source solutions like Hashtopussy are not flavors of Hashcat, but rather are all wrappers around Hashcat.
Hashstack, on the other hand, is a commercial fork of Hashcat with enterprise support, and is not only blessed by Hashcat, but developed by some of the same people that develop Hashcat. So it remains the only genuinely-supported distributed flavor of Hashcat.
