I can't comment on either of those campgrounds as we are retired military and stay at Ft Tuthill rec area when in Flagstaff. We lived in Sedona for a few years and went up to Flag often. Beautiful place, low crime, college town (NAU) and VERY snowy in the winters. Very common for I40 to be closed several times each year due to blizzard conditions. IMHO, I think I'd rather stay in a Pennsylvania open-year-round campground than one in Flagstaff!
That said, we HOPE that the forest fires now raging SW of Flagstaff will be under control soon and that the beautiful Ponderosa forests will not suffer too much damage.
