Watched the Ballard segment, and I would say not much science was presented. They do make claims about how the body best works and what is stressing parts of it, but I can't answer about the correctness of that.
In summary, the Ballard swing has the following points:
Feet Setup: Right foot square to line or in, left foot canted out
Stance: wide and tall. Inside of feet = shoulder width. No bend over in back (or very little)
Elbows Setup: turn elbows in, hold againt ribs.
(note elbows being in prevents over rotation of LAFW)
Backswing: Coil, no sway
also: elbows bend up.
Downswing: reverse the above
Claim: in a swing with axis tilt, it leads to hitting up and hand release hooks, or block saves.
What I saw of Rocco's swing: They make the swing out to be super simple, but the important things to me are left out, and in slow mo you can see the swing is not so simple. At the top, Rocco's club is toe down. In the downswing no major actions happen until his hands are about a foot from impact position, where he rotates the left like crazy and quickly releases all right wrist bend so that 1 foot from impact his right hand is totally flat.
For the average golfer, without being told what to do with those hands, it's right city.
