Beav, the real answer depends on what your goals are and what your other opportunities are.

I know plenty of guys who the ART system works great for. But they have different goals than me. The ART system provides a much better road for promotion and career progression if you're willing to fill your squares and especially if you're willing to PCS a couple times.

On the other hand, they're squeezing all the good deals out of AGR and TR jobs. AGR always sucked for promotion opportunities.

What do you want to do with your career? If you want to hunker down and be a major-for-life-in-place...that's getting a lot harder to do.
