In the South I would go with a machete.
I chose a machete. I live in SE Alabama and the machete does what I need it to do. It is lighter and more versatile. I modified it the way that Mac shows in his videos and it works like a charm. I chose a 12" Ontario. Put a shaving sharp edge on the first 4" of the blade and a convex edge on the "sweet spot. Squared the spine near the handle for scraping tinder and striking a fero rod and rounded the rest of the spine to allow me to use it as a draw knife.
I've successfully made one stick fires with it. The squared off spine makes dandy tinder from Pine. I can baton it to split wood and do light chopping.
I then made a simple kydex sheath for it and when it isn't being used it rides behind the back seat of my F150.
I did, however, also just acquire a Wetterlings 20" Axe and it is a delight to use. I wouldn't cry if I had to use it instead of the machete.
