Disting NT is a much better module in every way than Disting Ex (I can't stand the latter).
The interface is still horrible and takes some getting used to, but the large screen allows you to see the whole menu, so there's a pretty good chance of figuring out what algorithms are doing when Disting Ex required mandatory documentation browsing.
The architecture of the module is amazing. With Disting Ex, the possibilities were limited to a single selected algorithm, here the module is essentially a set of buses to which multiple basic algorithms can be applied in any order. The buses are visible on external devices, so the module can work as an audio interface.
It also has a simple and clear API, so that if necessary (and feasible) you can add functionality that is missing in the module.
Disting NT could have a better interface, some algorithms could have a simpler implementation, but all can be forgiven for its versatility. Also Expert Sleepers modules have long and good support, there is an API that will allow you to add necessary functions, all in all, this module is definitely worth it.
