Over all, Cyber Commander will be less expensive. However, many Photographers are already invested in the PW system. Also, it will allow more interoperability with other brands of flashes that will also allow power adjustment. It will have a more limited amount of control over the light and as best as I can tell, will not run the entire range of adjustment on the Einstein (do not quote me on that). Both have their place, and I expect some photographer running both systems for different applications.
1. How much control can be achieved on an Einstein with this unit?
2. As for the question of how/why to use this product, I am a good example. I already have Dynalite studio strobes with built in PW. Sweet! Now I have an Einstein/mini lithium as a strictly portable solution, and I have 3 Nikon speedlights. Going to CC doesn't make sense for me. I already a big investment in PW.
If the MC2 will allow me to control the Einstein as a key light, and then using the PW Flex TT5, also control my speedlights, then I have a true totally portable, multiple light setup.
