I think one has to look upon them in terms of what they were meant to be: two complimentary courses, one fit for tournament play, one fit for a more relaxed style of play.
I honestly thought Pine Needles was more difficult before the restoration/renovation, with the smaller more crowned greens. The new layout might be closer to the original, but all the greens seem bigger and flatter. Despite this, I think PN is a great tournament venue for the USWO, and for high-caliber amateurs (probably short of the US AM though).
Mid Pines is a charming, shortish course fun features that test your short iron play with subtle contours and elevation changes. The par fives may be reachable, but each one presents a long second with a bit of awkwardness to contend with. I still maintain that MP has more "fun holes to play" than PN. Holes like #4 with the fall-off angled green, #12 with the weirdly-shaped green, and #18 with the tight drive, great green, and Inn behind the green.
