The Jag's output curve is just as "smooth" and far more linear than the Vic's, as can be seen here. The putative compatibility problem of Jags & window motors has been widely discussed but the underlying cause not definitively understood AFAIK.

The higher PWM output frequency of the Jag causes somewhat less motor heating (for the same output torque) compared to the Vic, for some motors at slow speed.

And making a victor go bad is quite difficult.
I guess we are using a different vocabulary. In engineering parlance, that's not a performance issue, it's a reliability issue. Handled properly (read: don't pack them full of metal shavings and don't reverse the battery polarity... reasonable expectations) and used in a properly-designed system, black Jags have had a good reliability record for many teams.
