Back-EMF monitors the voltage and current on the motor to keep a constant speed regardless of gradient - if you take a heavy train down a grade with a Back-EMF equipped loco it will maintain a steady speed rather than running away - likewise, when climbing grades it will not require you to open the throttle any more to maintain a steady speed. This is particularly handy on locos without flywheels as it allows better slow running than would otherwise be possible for switching, as well as the previously mentioned benefits. BEMF decoders tend to be more expensive though, so you may decide you only want to invest in them for certain locos (I intend to fit my British steamers with them when I go DCC, along with a few other locos that have trouble with crawling along for switching work). Hope this is of help!
