I believe they both use the same delay chip (PT2399) which is OK but which "quality" or limitations make unfit in an instrument commanding such a price in my humble opinion. It would have been awesome with a DSP for instance, which we know Make Noise master since they released the Mimeophon which is freaking awesome. I think they make people pay for limitation, design, and Cortini's name, as comparatively speaking, a brand new Lyra 8 is also cheaper!
Anyway, we all have different expectations about that stuff but this was the first time I was disappointed by Make Noise.
And I don't think the keyboard argument is valid. The Monotrons have ribbon-controllers and are in no way usable in quantized ways. They're so tiny you can't use their "keys" as such.
