Personally,
I use a woodsman's pal and a Wyoming saw.
If traveling lite, then either a pocket chainsaw or ultimate survival (defunct) pocket saw.
Only in camp to we use a hatchet. Machete is great for the jungle, but in the marsh a woodsman's pal is the right size.
The Wyoming saw (or the Gerber that's about the same) is just fine for the larger size branches that are too big for SAK or Multi tool.
