I know this gets attention from time to time, but I'll drag it up again...
What's your view of the machete format? Do you have one to clear brush all day? In a "bug-out bag"? For zombie defense? Because it was featured in a survival show? To cut pig carcasses in half?
What do you expect from your machete and which one gets it done for you?
I own a few different machete-like tools: My most useful is a Tramontina with a slightly shorter, broader blade and no exposed rivets on the wooden handle. It carries a bit more momentum than a more conventional blade pattern for chopping limbs (as opposed to soft material), yet has plenty of reach and still has thin enough blade stock to pass through the items I cut with it, which is mostly light brush work. Another feature I like about this one is the soft, but not *too soft* steel, probably low 50s HRC, it doesn't dull too quickly, but sharpens up easily with a file. I also have a conventional pattern Tramontina, it loses out mostly because the rivets and unfinished edges on the wooden handle are a bit harsh on an un-gloved hand.
My second favorite is a large Woodman's Pal, it's got extra reach and a small brush hook, but the edge length is short and you can apply more force with the excellent two-handed handle than the thin blade stock can take without bending when it meets hard material.
Next up is a WW2 era Aussie Military pattern Machete, this one has steel that's a bit too hard for quick hand sharpening and the blade stock is thick enough that the overall weight makes extended use fatiguing.
Now for the "best" machete I own. it's a KaBar with a Parang type blade: it has 1095 steel in the mid to upper 50s HRC, excellent handle ergos, powder coat to reduce corrosion issues and wait for it... a .25" thick spine with a high sabre grind that makes it utterly useless for anything machete-like, it's more of a super-sized camp knife, or knife shaped hatchet, it's thick and heavy enough that it isn't even a good limbing tool, since it binds in wood worse than either an axe or a more conventional machete.
