The major difference between the two boards that you provided a link to is that one is USB and one Ethernet. I had a lot of issues with the USB version of the Smoothstepper. These were due to electrical noise from the spindle VFD. All of these problems went away when I changed to the ESS, using Ethernet instead of USB.
Re your missed steps, they may not be addressed by changing the motion controller. Missed steps are usually caused by the machine being on the borderline of the driving force that the steppers, drivers and power supply can produce.
So while an improved motion controller would be good, I'd look for your immediate problem of missed steps elsewhere.
