Ogre is basically the same bike but with more braze-ons to carry things and slightly heavier tubing so it might be a better choice for bikepacking.
There is likely a re-vamped Ogre being unveiled in the very near future that has a non-suspension corrected fork and possibly more tire clearance. Look at the current Surly Troll and imagine it with 29" wheels and that's what the new Ogre is speculated to be.
