I wouldn’t consider any of the analog complex oscillators or STO or 0-Coast to be brittle sounding, just buzzier or glassier or with different low and low-mid content and band-limited or not characteristics.
I consider the DPO kind of gray sounding in a good way with buzziness and rubbery bass, lots of low bass too. Less fat than the STO, which has a different variable shape than DPO, and the 0-Coast is a bit more lithe. DPO has vactrols all over inputs.
Whereas the Verbos has a lot of low mids, saturated rolled off highs and all sweet spot in the wavefolder, and vactrol slew in the mod bus. It sounds much dustier than the DPO, particularly the earthy AM.
The Furthrrrr has a lot more range on wavefolder, and is tighter than the Verbos, quite a bit of low mid content but shelves lower than the Verbos and can do molten glassier and hollow sounds but is never harsh really, and highs are somewhat rolled off.
The Cs-L I think is the most hifi, not very bandlimited and with a full spectrum ton of midrange content.
I agree with Starthief, go for sound primarily. Functionality is less important, more a convenience thing than a hurdle jump. Verbos it’s good to have another sine oscillator nearby for bipolar and linear FM, though. I usually use a Dixie for this.
Also pretty much agree with mritenburg’s assessment here, that the Furthrrrr wavefolder at least sounds like 259’s whereas Verbos in total sounds very much like 208. Albeit Verbos is exponential FM bus and unipolar mod osc.
