This is an old photo of mine when I had the ARB bar.

From what I can tell the XROX does not sit quiet as low as the ARB (even though it looks that way with the flat face of the XROX) and it definitely does not sit as far out as the ARB.
I am certain the approach angle is better with the XROX and it opens up the front tyres a lot more to give better clearance too.
