Alex -

For all purposes, you can assume they do operate -1 to 1.

The source of this misconception is that the Tan jaguars spend a very small amount of time in the "off" state to re-charge part of their drive circuitry, even if they are commanded to go 100% on.

However, this is transparent to the end user. "1.0" still refers to full forward, and "-1.0" still refers to full backward. Without an oscilloscope, you wouldn't really be able to tell.

The natural followup is "how does this compare to the Victor?".
I would argue that this is almost imperceptible, and washes out in the end.
1) At anything less than 100%, it is irrelevant.
2) The Jaguars' FETs are slightly better and have a lower resistance. This means that for a given on percentage, they can give slightly higher power to the motors.

But really, these differences are completely buried in the noise. Any gear box is going to have an impact easily an order of magnitude greater than this.

The reason that Jaguars are typically perceived to be "slower" is that they have a very linear response, whereas the Victors have a non-linear response that is "punchier".
