Square Groove rifling vs. Ratchet..

On another post there was reference to Rice Barrel company.

They apparently offer "Square Groove" rifling.
It appears they are making barrels for the Muzzle Loader type fire arms.

That said does anyone have experience with either Square Groove or ratchet type rifling in the Center fire Single shot realm, good,  bad or..?

I noticed that there is some discussion in the rim fire world on this subject.
Here is a link if interested

Last I knew, most barrel profiles CF are square,
I shoot RFBR/CFBR, Hart, Bartlein offer 5R barrels, I shoot both. Bartlein being gain twist as well.
RFBR barrels are offered in every flavor imaginable, square, ratchet, MI. Have shot them all.
This said, there has been zero proof any particular profile supersedes the quality of any particular barrel, this, again, in the BR world fit to the most precise rifles made,
