Jud,
I disagree with that statement to a point. Sure it may have been harder for the GCA to screw up the course, but it's so much easier for time to have taken it's toll on the course. To me, an uninteresting hole or two is no worse than an old course choked by trees, bunkers to be grassed over, and fairways and greens to be shrunken to half the size.
In all seriousness, there are so many variables to different courses. If all things were the same, I'd make sure I could play both courses. If it was a one-time play I'd go with which architect I liked more. If the architects were both unknown or similar, I'd flip a coin.
