Having just cracked open my 2009 bottle of Westvleteren 12 to celebrate passing the bar, the flavor of that beer is fairly fresh in my mind. I have to say... not any better than Rochefort 10 or St. Bernardus 12. In fact, I had a St. Bernardus 12 right after my Westy, and found it slightly larger in body (which I liked). If it were my tastebuds, I would go with pils, some munich, a little caravienne, some special B, and then D2 - like a bigger dubbel. I guess it would be something in between Rochefort 10 and Westmalle Dubbel, but that doesn't sound like a bad thing to me.
