Ethernet smooth stepper with mach 4 retrofit?

Has anyone upgraded to the ess and mach4? My thought is that adding thc will be far more customizable using these options. I haven’t bought mach3 yet and I’m winding if it’s worth going straight to this option. People say the ess is far less prone to interference this usb based controllers.
Info on thc with Mach 4 and the ess (1000hz feedback loop for thc)

I’m very interested in this as well. I’m looking at the Warp 9 design Ethernet smooth stepper and the TMC3in1 THC module…would love to know if anyone has gone down that road…
