I've played both courses, and while I find Duke a more varied and pretty course, I almost like the Championship course at Tanglewood better. I played it in Mid-March, and the brown, dormant/dead rough made for very interesting, off-fairway adventures, usually involving the clay-sanded red-brown-orange bunkers. A very striking contrast in colors.
It appears to me that there is mostly negative sentiment towards Robert Trent Jones, Sr's courses, but the aforementioned are two courses I enjoy very much.
Why no love for RTJ?
