I have handled both, they are very different, and both focus on a specific purpose. The GGG Battle Hawk is more of a breaching axe that can be used for offensive purposes. The Sibert Comanche Tomahawk is a pure fighter, but can be used for some breaching purposes. I choose the Sayok Winkler Hawk over both of these hawks, it fit mi needs, and the quality is just beyond that of this two hawks.
The GGG Battle Hawk on a side note, isn’t that good at what it’s made for (breaching) id go whit an RMJ Shriek for that.
If a fighting hawk is what you’re looking for, go to Winkler Knives II, for a breeching hawk go to RMJ Forge.
