I personally wouldn't touch the 660/12 FG unless you're in love with the color. Before considering the MG, I'd ask for photos of the actual guitar, especially if having figured maple is important to you. The link in your post is a picture from the RIC website and you should not assume the new one they have in stock looks anything like it. The 660s that have come out of the factory the last 12-18 months haven't had as much figuring or character as in previous years.
I personally like the v64 for all the reasons others have stated. Take a look at the string spacing between pairs on that guitar and compare it to the FG 660, it's like night and day.
Good luck, both with your decision, and with sorting out all our opinions....
