    Why would anyone buy a LF model if it is not only for the gain of 0,2V for minimum RAM retention voltage?
    Because some LF versions will work at significantly lower operating voltages.

    Consider something like a PIC18LF2431 which will work at 2V with up to a 4MHz
    oscillator. The non LF version requires 4.2V minimum for any oscillator speed.
