We use that one also. It has an option to completely remove ("do not store") ip addresses for usergroups you select.I tried that one. It hides, but not removes. It allows admins to see the IP. Mind that you need to make moderators admin to let them moderate things like new users. So most moderators will still see IPs which defies the purpose.
If I remember correctly it is possible in Xenforo to assign permissions to single users also.Yes, I need that on per user basis so that I can completely remove superadmin IP and possibly some others, but still store IPs for other admins.
