I have a 22" Ontario which I keep on hand if needed--but it seldom sees usage since I got a Tramontina bolo. Here is the Bolo I have.

I also bought the 14" Condor Bolo leather sheath which fits it very nicely and makes it nice to carry on your side. The sheath costs more than the machete but I much prefer leather over canvas.

I really like the thinness and toughness of the Tramontina and the carbon spring steel for field sharpening. The spring steel is made to take abuse and based on what you pay for a Tram you don't mind using it hard. I blued my blade for rust prevention. I also mildly sharpened the top side like a Bowie from the end of the Bolo to the point for better sticking penetration. This also creates an upswept point on the bottom side for a skinning point similar to some of the old Green River Butcher knives.

The Tram should work pretty good for carving up a wild Georgia pig roast. I also square edge the spine above the handle for use with a fire striker.
For me the length is just right for carrying--I don't like anything longer than 14" for a regular carry on the belt.
I like the traditional wooden handle so it can be sanded to fit the hand correctly so it does not chafe--then I oil finish and wax it. The Tramontina blade is thin and well suited for briars, brush, and grass and yet heavy enough at the Bolo for hardwood limbs. I usually wear leather gloves when using it on brush or briars since it is shorter than a typical length and you can occasionally have a branch/briar whip your hand, but its shorter length also provides more precision in tighter quarters. The Bolo portion allows for pretty decent chopping on larger hardwood limbs once you learn to use the weighted sweet spot. Its thin enough and weighted enough on the Bolo to give surprising penetration on heavier wood. Its about the right length batonning/splitting wood and kindling. The thin 14" Bolo is my favorite all-round carry machete.
If I want something with more heft it would be my customized Condor Boomslang.

I removed the epoxy paint and blued it for less penetration resistance, and thinned/lengthened the bevel of the cutting edge and Bowie styled the end of the blade. This thing will out perform a machete hands-down as a heavy duty chopper and can still serve as a big Bowie sticker or large skinner and can also be easily carried on the belt. The handle has great geometry for heavy controlled chopping.
IMO the Condor Boomslang excels for chopping and the Tramontina Bolo excels for the lighter brush.
The 22" Ontario just stays sharp on the shelf because its too thick for efficiency on light brush, grass, and weeds compared to a Tramontina (or typical South American) style and less effective than the Boomslang as a heavy chopper.
You asked about a bushcraft machete, not home brush clearing tool, not a sugar cane harvester, and not a heavy chopper, so my recommendation is the Tramontina Bolo for all-round Bushcraft usage on the trail.
