What I know about bracketing with exposure compensation is it's useful in high contrast conditions in the frame - typically bright day with objects in deep shadow, or sun shining though foliage over your main obejcts for example. If you want to capture a higher range of light and detailed objects, use bracketing with + and - exposure, then use software to overlay the taken shots. I've seen brilliant photos taken this way.
