I've had one from each of the "big three" for many years now. There have always been one or two things that one brand does better than all the others. Once I figured out how to drive the second arranger's style engine with output from the first, a two-tiered, two-arranger setup became practical. When I decided that was too much visual bulk for the dining room, I switched to an arranger and a module. Frankly I don't care if they ever make a better model because I'm pretty content with what I have. Not selling any of mine anytime soon.
