Really depends on what you want to do with it. I don't have much experience with the more traditional thinner machetes. About all I can tell you is that I personally love a nice distal taper and high rc on thinner machetes. I believe Tramontina makes one of their Bolo Machetes this way.
But I do know for a fact that its hard to beat the Cold steel Kukri Machete If you want something cheap and indestructible. It is 1055 steel, but the black coating is actually incredibly durable. It is 55rc, so its easy to sharpen any where, and The Machete itself is as tough as they come. Its 16oz, so not too bad, but still a little on the heavy side compared to some of the traditional styled machetes out there. Only downside is the grip. While I doubt it would ever fail in any way, it does get a bit slippery when wet and is prone to causing hot-spots on your hand. I wrapped mine in gutted 550 cord. Problem solved. The newer Machetes have pretty nice sheaths too. Its plastic lined Cordura all riveted together. The older models used to not have the plastic and were complete garbage (although I doubt you can even find them for sale anymore).
