Both are selling first gen gear and have no other hardware out under their respective organizations 
HashFast has completed logical and physical design, paid their NRE, taped-out a very complex chip in record-breaking time (over a month ago), and expects their TMSC wafers to be done next week.
Cointerra might have done some of those things, but we don't know. In any case, Cointerra's chips won't be here for another two months, at best.
To summarize for the TL;DR crowd:
HashFast - chips done next week
Cointerra - hasn't even taped out yet
Can't wait for chips!
