Ive been running a front singletrack rim that has outlasted many other bike parts throughout the years.
But if I had the choice of the three, i would most likely take the D521/721 as it seems to be the best weight/stregnth ratio rim. I ran a rear one for the last 2 seasons with no problems as well. Mind you, im not really that hard on wheels.
