Depends on my mood and Odin's. Sometimes I hail Odin, Lord of war, battles' strife and victory, others I honor Odin, master of knowledge, death, arts and mysticism.
There is another aspect which IMO can be talked about distinctly (even though all three overlap greatly). It's Odin as "the whole one", "the cosmic one" or "the mighty one" and Odin of the "mighty pillar", being the Allfather, inventor of societal order and progenitor of royal families.
How the Germanic peppers viewed him is way is found in the history and reconstructive lore. He was originally PIE Xārjomēn/ Leughjos ("tribal unity/oath"), lord of social order, healing, magic, the mind, oaths, the crossroads, merchants and death. Then something happened as he became Ur-Germnc Ermunaz/Leugjaz ("cosmic/unified one"/"oath"). The people sought his magic to win wars, parallel to the celts with Lugus, and as lord of war and victory he was given the name "Wōdhinaz" ("master of rage/divine mania/poetic fury") as the magician who decides the fate of battles and warriors. In the same period, Leugjaz changes its meaning from "oath" to "lie" and eventually is viewed as an independent entity. His name Ermunaz continues to be used until the Viking age but declines in popularity. He's venerated as this aspect as the divine ancestor of the Teutonic Germans and Anglo kings as well as the founder of the indigenous culture, traditions and law.
For Old Norse, with Leugjaz, the eu- shortens to an o-, the g- changes to k- in accordance with Grimm's law, -az is dropped to fit the grammar and consonant j- lengthens to vowel i-, which spells Loki.
Most germanically originally, Odin is Wōdhin, The Magical Warlord, bringer of victory, berserkers' madness and strength, Ermun, The Cosmic Culture Hero, lord of chieftains, social order, culture and society, and Leugi, The Shamanic Seeker, god of the cosmic crossroads, magic, travels, knowledge and guide to the souls. It's Leugi who would seek the runes and well of wisdom before he was called Gangleri by the Vikings.
The way I see it, this is a good way to understand the Allfather as long as it's remembered that this is simplified and he's much more complex and abstract. The Cosmic Culture Hero is also patron of shamans, having been those who would settle legal disputes or community conflicts, who also practiced magic. The Magical Warlord also was fond of mysticism and cause conflict between nations to result in war. Leugi is a trickster causer of conflict and magician as well. The Shamanic Seeker shares the role of death with Wōdhin, who was Odin as the chieftain of Asgard, overlapping with Ermun the father of kings.
Looking more closely we see all three are magic related, two arguably trickster, one culture hero (two closely related archetypes), all reflect different skills and influences of Germanic shamans (victory magicians/ legal councils/ journeying, spirit workers). To put it simply, at his core, Odin is a trickster and culture hero of magic and the crossroads of the worlds, and everything else is interpretation or variation based off of those roles.
