Prophet~6 Distortion vs OB~6 Distortion

[MPM]

Reposting from OB~6 board
I've noticed a difference between the way my OB~6 and Prophet~6 Distortion effect sounds. When applying distortion to an initial patch on each synth (with a simple filter env for musicality) I find that the Prophet~6 distortion sounds lifeless compared to the OB~6 distortion, which sounds like it's following the notes and much more musical.
My question is, are the OB~6 and Prophet~6 distortion circuits identical in both synths? In which case I assume something is wrong with my Prophet~6 distortion. Anyone with both hearing the same thing?
Or are they just wired in differently?

naively I would say that the oscillator shapes are different when compared, so it's not surprising than applying distortion to them would be a different timbre. Not sure about A : B direct comparison but I'd be surprised if it was different. Maybe they have different gain staging?
