There is no better. It's up to you and your taste. If you like the effect, leave it on. If you don't, don't. That's why it's there as a feature - for you to use, or not use, as needed.
I would say case to case basis =) there are instances where you need DRO to be on even max out just to get a good image but make sure your ISO is controlled else your dark area will turn to gray and noisy
