The HID is brighter but I don't beleive that's the reason that you have to aim the headlamp assembly down, I think it's because the OEM reflector (which is not designed for an HID bulb) scatters the light a whole lot more.
So even though the HID was brighter, after aiming it down there was little benefit, maybe the primary advantage to installing an HID on a R12GS would be reliability, which I hear is normally much improved vs an H7 bulb, but on my bike I was typically getting 20-30k miles per H7 so not a big issue.
