Jonathan,
Between Wilmington and Spyglass, they are so different I find it hard to compare, although I did play both this year. I actually like Wilmington, probably just due to the difficulty factor. In the minority on this website for sure. I'm a member at Aldarra, so I'm obviously biased, (and I'm normally not a huge Fazio fan, with the exception of World Woods and Galloway), but it is quite a good golf course IMHO.
