Seems like you're looking for a chopper more than a machete. Machetes are longer, thinner, and excell at cutting vegetation, grasses, brush. Sure, they can chop wood, but there's a point where it's just better to get an axe, hatchet, or hawk.
Something like an Ontario, the 1/8" thick ones, are pretty good choppers, and a bit heavy for lighter vegetation. If you need a thinner blade for machete tasks, like clearing trails, there's lots of options, mostly from Central and South America.
Condor, Imacasa, Martindale, Tramontina, all make affordable machetes. Then, it's just deciding what blade profile, length, and handle type you want.
Then there's the modified Imacasa's, like Fiddleback Forge, ESEE, or the Blind Horse Knives machtetes. These are more expensive, but they have micarta handles, and some have better sheaths(Blind Horse seems to have a great sheath).
Kukri's are choppers, just too heavy for machete work. Yeah, they can do a job, but so can a machete. It's just a matter of how long can you swing the tool that's either too heavy or too light for the job?
