The economy Ontario is about the same thickness as a Tramontina. However, the one I have came with an incredibly thin edge bevel, about 10 degrees inclusive. And the steel seems tempered harder than the Tramontina. These things lead me to treat it a bit less rigorously. Ontario has a rep for inconsistent heat treat, so any particular sample may or may not be as hard or soft as the next.
In the end, blade thickness of the machete in and of itself is not a serious factor in it's suitability for batoning.
