here's my take. if you want to spend more money than a tram, imacasa, condor....do it. no one needs a good reason to spend more money, for better finishing and prettiness.
if you want the machete to do work and just want one that can get the work done, pretty or not....no reason to spend big bucks on a tops, fiddleback, bark river, or other higher end in finishing machete, imho.
i like the pretty ones, but when i want to do work i grab one of my trams or imacasa's, cause they work, and will get the job done as well as the expensive ones.
i prefer the standard, collins, bush, latin (pick your favorite name)shaped machete for general work......myself.
as always, ymmv.
