Let me tell you from experience and owning trucks with both:
If you are running a doubler you will have no need for the NP435. If you are running a single transfer case than the 6.30'some ratio of the first gear granny low will be helpful.
It would also be nice if you told us what you were planning on doing with the truck, what tire size, and what gear ratio you were running.
If you run a doubler, you are better off with a ZF5 speed transmission for the better gas mileage, since you are easily able to double your low range twice over (each transfer case) With the NP435 you will have no added benefits, just basically the loss of 2 gears, and worse gas mileage.
Also, the ZF5 and a 205 will do fine for mudding and basically any and all terrain. Even rock crawling. Unless you need incredibly low gearing the NP435 or the doubler won't do you much good.
