I may not be one to ask, because I chose Erica’s Techno System for my drum machine ; ) It is really worth it for what it does, and it is a joy to play. What it does NOT do is set and forget. It’s much more its own instrument/mini studio. That said, I’ve thought hard about getting Queen of Pentacles or Quad Drum Voice to add to my regular rack, leaning towards the latter because of its size and convenience. I also have a TR-8S which I love but don’t integrate with my modular unless it’s going into a sampler.
