Qkeys
I have used both Uniden and GRE/Whistlers scanners since the RS Pro-4 got me interested in scanning. My experience is that the GRE/Whistler system is easier and quicker. On my Pro-106, pushing a number key tells me the name of the system at the bottom of the display both to turn it on or off. The V Folders can be labeled with real names, making them easy to select and change. Without a cheat sheet, the qkeys will never match the simplicity of the 106. On the newer GRE/Whistler scanners, it is a different process, but everything has real names, either assigned by the database or by your choice. Scrolling through the database is a little slower, but no cheat sheet is required to turn things on and off.
