I've come to the conclusion the Zenesis is the same as the Darwin or Opus, you have to really know someone to get one.... Been trying to get a Darwin for over a year and Zenesis for 10+ months now and have found it virtually impossible.... Even when I have seen posts of them being in stock and checking 2 minutes later, they are gone.... I to this point have given up all hope of it.... As to the question of which is better, whichever one keeps you off analogs!!!!!
