Without watching all of your video, I'll offer one of Ron Kulas' (the StaySharp broadhead sharpening guide guy):
My takeaway:
As per Dr. Ashby, an arrow is always flying between launch and when forward motion stops; it may fly through the air, an animal, or a few inches of dirt or tree trunk, but it is flying. As such, when it is flying through the air, its rotation is controlled by the fletching. Once it starts flying through meat and bone, its rotation will be controlled by the broadhead. While foam is a poor substitute for meat, it does serve to illustrate how broadheads react when flying through something more solid than air. This video shows that broadhead rotation through meat is controlled by the bevel, not the fletching. So, neither a double-bevel broadhead, 3-blade, or 4-blade will rotate any appreciable distance through meat. If rotation through meat is important to you, you will need a single-bevel broadhead.
To answer your question:
As per Dr. Ashby, a 3:1 ratio, double-blade broadhead will penetrate deeper in game than any other design. A single-bevel, double-blade broadhead will achieve superior penetration through bone than any other design. I'm not aware of any information suggesting a link between depth of penetration, and whether or not a broadhead rotates through meat; the advantage to rotation is twofold: splitting rather than puncturing bone, and more surface area cut in soft tissue. I would expect that two equally sharp, otherwise identical broadheads, 1 double-bevel and 1 single-bevel, shot through soft tissue, would penetrate about equally, regardless of rotation.
As I apply my understanding of Dr. Ashby's research, a larger cutting diameter - be it from a 3-blade or mechanical or extra-wide two-blade - will be achieved at the expense of penetration. Now, if 1 head is good for 36" of penetration and another is good for 48", but both are shot at a broadside doe 18" across... the benefit is moot because both passed through. The penetration advantage of the second broadhead would only be realized if the doe were to duck the string or spin away from an 18" broadside aspect to a hard quartering one.
So, what broadhead should you shoot? You buy what you want with your money. I shot 3-blade Montecs for years and am switching to single-bevel Maasais and Grizzlies on my wheelie bow for adult arrows, and Magnus Stingers on my backup Twizzlers. Wenzel Woodsman 3-blades are very popular and are similar to the VPAs, the Cutthroats and Tuffheads also look excellent.
If you have Stingers that fly well on your arrows, my advice is, MN season opens in like a week; shoot what you have this year and spend the winter and next summer building up another setup if you decide you're not satisfied with what you have.
