Zen was just released. The software behind it is hands down next level especially the new anologe commands. U can do vast more with this than the titan two. The software has more flexibility in programming more complex scripts and the memory is next level on what u can fit in a entire script. Theres way more customization like the oled screen that can work in conjunction with scripts to give u visual display on your setups ect. If you read up on both u can make the decision for yourself. I personally love the zen.
