I like the marbles a lot.
I guess its the most complex and easy to use random module, while you have Instant access by tweaking knobs.
If you understand it you can archieve incredible results.

The selfpatching abilities are great and you can get endless evolving random cv and gates.

The fact that it is like a kind of turing maschine comes really handy and makes it very playable.

Another idea cold be clank chaos.
Chaos seems to me more drastic and chaotic. You get a chaotic random mess and can thin out the chaotic cv and gate results afterwards to fit it to be less what you not want and to be more musically.
It has also a cv looping feature and got a sequencer ability in the new firmware.

I have both and enjoy them.

I use the marbles to dial in controlled random for basic and dominant functions. The chaos I use for glitchy, unpredicted and wild random.
