Weight doesn't always equal better chopper. Thinner knives bite deeper, and require less effort to swing.
MM raises a valid point.
IME there are a few factors that make for an efficient chopper, if "efficient" chopping is your definition of "best" chopping, and contribute or detract from the chopping experience. Those factors are (in no particular order and often interacting with each other):
- blade geometry
- edge geometry
- blade length
- overall length (OAL)
- total weight
- weight distribution
- handle ergo's (MUCH more important than usually acknowledged)
- penetration, as MM mentioned
- rough/smooth bevel surfaces (friction)
- chip clearing from the cut
- spine thickness (related to geometry)
- spine-to-edge dimension (also related to geometry)
- material getting chopped (light whippy wet-green grasslike stalks up to dried hardwood)
- and no doubt a bunch of other ones I've forgotten
The material consideration gives the advantage to thin, long, neutral-balanced blades like a machete when cutting light whippy stalks. In this case there isn't a lot of stopping influence from the material getting chopped and you need to brake the momentum with your arm/wrist/hand muscles. The heavier the blade, the greater the momentum you need to counteract. This would influence MM's CS lightweight machete choice over a FFBM in this type chopping.
For these types of materials, most Busses fare pretty poorly. My favorites for this type cutting are a 24" carbon-steel bladed WW II military machete (a little over 1/16" spine) and a 19" OAL, hook-nosed Gerber Brush Thinner. FWIW, the Gerber's light weight, length, and axe-handle-shaped handle make it quite comfortable for extended sessions of whack 'n chop in blackberry bushes and other such stalks. It penetrates quite well into green wood as well, even better than a fat Busse on frequent occasion, but is such a major PITA to extract from the wood due to lack of bevel on the blade that I don't use it on wood.

But when the material is a hard, rigid substance like dried hardwood branches or rounds that need splitting, the advantage goes to Busses and other relatively fat blades with lots of chip-displacing primary bevel to blow the chunks out of the cut. In this class, the kukris (some over 1/2" thick) really shine. However, their total weight works against me wanting to carry one, especially on my belt (vs in a pack). In this regard, the bigger Bussekin knives (BM's, Basic 9, NMSFNO, SH, CT) are my choice for a blade that will chop and cut well, but still not weigh me down like an axe or kukri.
As with so many things, a Busse gets the nod not so much for being a huge quantum leap above the competition in any single area, but rather because its combination of qualities makes it the tool of choice. Its versatility in handling a very wide range of chores, often unspecified at the outset, is its strength and IMHO the reason my "only have one knife" list is populated with Bussekin blades.
So, to answer the question "Which Mistress is the best chopper?" ----- whichever one you have with you.
