I can't say anything about Currahee, but I too really like Cuscowilla. I can think of few golf courses on which I would like to play match play. 5, 8, and 12 are splendid 3.5-pars (par 4, 3, 4). I do, however, belive that #11 would be greatly improved aesthetically with some trimming. To me, #14 is extremely awkward the first time around. I feel that the proper play becomes apparent later on.
Of all the holes, #13 is my pick for most underrated. A bunkerless hole (and I love the look of the bunkers at Cuscowilla), the contours provide ample challenge as it is a nice, meaty par 4.
Having looked at Currahee's website, the golf course seems pretty unfriendly to the walking set. Cuscowilla is fairly walkable. Cuscowilla's features are also far more subtle, and it is nearly 1000 yards shorter than Currahee, which tells me there is a lot more intrigue to be found at Cuscowilla.
Finally, when I played it this past June, the golf course was in great shape. Pretty firm for a clay-based course, and the greens were quite quick.
