I haven’t had the opportunity to use Beads yet, but as someone who got into modular specifically so I could use Monsoon, I’d say that the two are very different. First of all, Emilie’s work on improving audio quality was apparently quite successful, and this is not something that any Clouds clone I know of even attempted to do. Longer grains, automatic gain control, etc are all impossible on those designs.
I expect to see some tiny clones of Beads, if/when possible; while I aesthetically dislike them, I understand their popularity and utility. Because of the assignable CV input, I do also expect to see some larger clones with per-parameter inputs, and perhaps per-parameter controls.
One of the few positive differences between, say, the Warped Circuits clones of Mutable modules and the originals is the use of half-minipots - metal-shaft potentiometers with metal caps for trimming, but smaller than a full-sized PT-PS Rogan knob and thus without a huge increase in HP cost. I expect to see clones which swap the trimmer attenurandomizers for these more durable pots.
Emilie mentioned on her forum that she considered a fader-based interface, but rejected it. I agree with that decision, but I still expect to see Monsoon or Typhoon-like clones which make the 5 main parameters available on faders.
So, in other words: they’re not really comparable, and if there’s the opportunity, I’m sure someone will come up with a module that is to Beads what Monsoon is to Clouds.
