Snowshoe definitely has better skiing (and gets more snow) but Wisp is more of a 4 season area given Deep Creek Lake. Wisp is also easier to get to which is why we decided on McHenry instead of Snowshoe. But Snowshoe definitely has more of a “snow village” feeling which I liked when we went there for my 30th a few years ago...Wisp seriously lacks that but does have stuff in the area in McHenry, Swanton, and Oakland.
You really can’t go wrong with either if/when you make the jump.
