I ultimately passed on the Hydrasynth because I used it as a basic VA synth most of the time (and sometimes as an FM synth), the wave morphing was interesting but many of the supplied wavetables weren’t that useful for me (and it was the desktop, I think I’d prefer the 49-key version).
Something about how it interpolated between the 8 selected waves struck me as strange, but I might not have spent enough time with that side of it. Wave morphing is a different take on WT really, and your interpolated steps might be wildly different based on the waves you pick. I guess you can setting on a few waves you particularly like and use it that way - wanted to be able to pick the 1st and 8th position and have it interpolate across all steps but that didn’t work (so felt, to me, a bit steppy between waves 1 and 2 if that’s all I wanted to use).
