I hate my Disting. I find the user interface to be just jacked and difficult to work through. However, it's a great module to have if you want to explore lots of different functions. I've used to to figure out what kind of modules I'd want to have complete versions of... like a quantizer or a comb filter, reverb, etc. It's also great in those "I just need one more (blank)!" moments... an extra VCA, an extra oscillator.
In all honesty, a Eurorack drum machine sounds great on paper. But once you start pricing out everything you're going to need, you'll find it to be an extremely expensive way to go... even if you get dedicated drum modules. That's a lot of money to reinvent a drum machine. I bought a 1010 Music BitBox to act as an in-rack record/playback system. Boom. All my drums. I can also record in-sync. So if I have a long ambiance, I can loop record it or any other part.
Beware the rabbit hole. It will suck your wallet dry.
