I got the chance to demo both units a couple of years ago when we were looking into these systems. Hands down, the Hurst (Moditch) is a much more user friendly version. My big problem with the Holmatro system is that it is essentially an encyclopedia on cd. There is little interaction with the program
The Hurst system, on the other hand, immediately brings up a CAD diagram of the vehicle, with all the hazards that you can click on to give you warnings. It is very simply laid out. I believe that you can also hook a wireless barcode scanner to it and scan the VIN number of the vehicle in question, bringing up the exact make/model/year without having to go through the menus.
Either program has a wealth of knowledge, and both work well, but I think the Hurst setup is much easier to get the information from.
