For those who care...
I go to Chestnut every Friday night since it's now my closest Park. I've also been to Devil's Head hundreds of times. IMO Chestnut is better for park with the Farside and Devil's Head has much longer and better runs but almost no park features. Chestnut runs are extremely short, like 30 seconds down. They are steeper (especially the blacks, which are steeper than anything at Devil's Head) but they usually have terrible snow - either really icy or full of skier moguls. Chestnut has a better view from the top if that's something you care about. The view when you get to the top of Devil's Head is literally snowy cornfields (both at the top and bottom of the hill). Devil's Head has a lot more trees and a little better seclusion between runs, whereas Chestnut is basically just a free-for-all snow field with a few tiny pockets of trees. Neither have a good lodge but Chestnut has the slight edge.
Also, yes the "black diamond" and "double black diamond" is all relative to the mountain out here in the midwest. At Devil's Head the double black is really the same (actually less) than the blacks at Chestnut, but because they use circle, square, diamond, double diamond, you get a better idea of what skill level to expect on each hill. At chestnut, blue square could mean flat or steep, it really depends on the run.
