Subject: Boosting exposure/reducing brightness or vice versa?

---

If I boost the exposure by +1.00 and reduce the brightness to 0, the image and histogram appear identical to the same image at 0.00 exposure and brightness around 60.

Is there any particular virtue in adopting either method in juggling the exposure/brightness values? I was assuming that as boosting exposure was around the same as doubling ISO value, it was best to avoid boosting the exposure unless absolutely necessary to avoid introducing unecessary noise.

Secondly, is there a "neutral" or starting point Brightness value? The "image default" value is 50, though I open most images using the Camera Raw defaults as a rough starting point.
