Forester – X-MODE

Hi. I am interested in the Forester – which I want to use 90% in the terrain, partly heavy terrain, for hunting and forestry. Now I wonder how useful the purchase of the X-MODE is. This is only available from the equipment variant XS automatic and costs accordingly. Or do you think the normal four-wheel is just as good? I understood this so that the X-MODE electronically determines which wheel has to be fed with how much drive, for a drive, especially with mud and I don’t have this possibility manually at all and I have concerns not to be able to overcome one or the other mountain, or mud-seams. Do you have experiences or do I understand something wrong?
