I don't own either, yet, but I just got accepted for the test team Regulator model, so I will have this soon. I am kind of torn on recommending one versus the other. I think that the masses have spoken about the chopping of the SOD, but the Regulator will be no slouch on this front, and will have some piercing versatility to its advantage. Both would be well suited around a camp, I think, and perform beyond most of our typical needs. If you want a knife to work over lumber, it would be the SOD. If you are taking survivability to more of an extreme, and want a knife to dig into a tree, skin or process game etc. and also process wood well, the Regulator would be the one that would shine.
