Transportation: Clearing trails, I usually use my Becker when I'm on a trail and it is blocked by vines or branches. If I move off trail I switch to the machete in dense brush but tend to resist it as long as possible. When I get hung up by vines the Becker does the trick.
Camp Clearing: Often in the lowland forests or scrub land I have to clear the ground of underbrush for my hammock. In light brush I'll use the Becker. In heavy growth I'll use the machete. If I'm going to sleep on the ground I'll often chop out roots and dig up rocks, for this I use the machete. It isn't as abusive as it sounds because I'm using the blunt tip anyway.
Shelter Building: I normally sleep with a bivy and poncho or tarp and hammock. Of the shelters I have built I much prefer the machete over the Becker. If you have to chop alot of stuff the added reach of the machete is a big plus. The Becker can do it but you have to drag the materials to a place you can work more upright like a downed tree.
Firemaking: In dry season I don't have to use any special techniques to make fire here, dry materials of every size abound. In rainy season it is a real challenge to find anything that will burn, especially small stuff. I have used all of my blades to baton open wood, the Becker is best for this but the machete is almost as good. I use the squared back of the machete blade to scrape up a large handfull of dry tinder from split wood. I often use the back of my Mora to strip off wet bark, make fuzz sticks, or split small kindling. I use the squared off back of the Mora blade to scrape my ferro rod. A folding pruning saw is far easier to make firewood than chopping with anything.
Digging for Water: Machete. I will often shove the machete down into sandy places and give it a twist to see if it comes back moist. If it comes up dry it pays to walk farther downhill than dig 12 inches of sand and gravel. I have done this with the Becker as well but I cringe every time I do it and I've only done it up on mountain tops when I didn't have the machete.
Small Cutting Tasks: Cutting cord, whittling, food prep, cleaning game, drilling holes, shaping materials, stripping bark, making cordage, etc, Mora.
