Odin's greatest feats outside of Asgard were his multiple galaxy destroying fights, one with Forsung the Enchanter and the other with Seth (it was the third fight between the two, the one where Thor's v1 became retitled Journey into Mystery again). Also there is the Infinity Saga where a shard of Odin was consuming and mindraping the entire 616 universe and then he undid the damage.
Of course there was dead Odin casually creating a solar system in thor v2, that was issue 60 or so. So this probably puts dead Odin above Thanos too.
Gungnir is not Odin's most powerful weapon/item. The Odinrod is. And these items serve to focus Odin's power so that he may control the side effects.
We did not see Odin go all out because Asgard was still there when he was done.
