as you said, its the drumkits that sound convincing, so its hardly about the device at that point.
i dont see any reason why you wouldnt be able to use such drumkits on a blackbox, as it provides all the needed tools to use those kits.
Example: take a high hat sample with 50 different hits, use slicer pad in walk mode (semi random forward advance), use LFO to slightly offset playback start, add a touch of built in reverb (which sounds great), modulate release with velocity, add it to mute group with a closed hat.
In other words, very flexible, but you gotta take some time to build those kits
