Having played most of the courses mentioned I would have to say that Bandon Trails will outdo Pacific Dunes. However I believe that Friars Head is a better course than Trails. I am just guessing, but I think GW's rankings will look like this next year:
Sand Hills
Friars Head
Pacific Dunes
Bandon Trails
Whistling Straits
Bandon Dunes
This makes me wonder if Bandon Trails will end up in Coore & Crenshaw's Top 10. I'd guess it might. So far... (from Bencrenshaw.com):
