If you do want to use the Oculus store one, go into your current one and save your skins folder, settings folder, terrains folder.
So you don't have to download all of that or setup everything again and once you get AH installed through the Oculus store just move those files back to their homes.
As far as SHOULD you be using that one? I can't really speak to that. I know there are some differences but I don't know if they really matter or if there are benefits. I know the patch system doesn't require any user interaction which is nice, with the oculus version.
