2022 Outback Wilderness
Assuming it works like my '14 Forester did, I used X-Mode primarily to descend a short steep hill with a turn at the bottom that leads to my house. I only bother when it's icy or snowy. It does a MUCH better job than I could do to keep my speed in check without locking the brakes, even with ABS. I just don't see a need when I've got good traction. Might make sense for dirt road descents.
