Talon SR vs Talon SRX vs New Victor vs Spark

[JHawk29]

The SR is more efficient than the SRX (by a marginal amount), as was documented by CTR. If you're OK with running PWM, there is absolutely no reason to switch to the SRX. That said, the SRX does have some advanced features that could be useful, if you aren't handling PID and other controls in your models (though figuring out PID controls on a motor probably isn't any more effective than just using LabVIEW to do it).

In summary, there isn't anything to 'upgrade' to from where you are.
