I did not know proto made a QR, or a round head for a matter of fact.
I think that in the past professionals feared Quick Release because they had (still do?) a drilled out center in the drivepiece/squaredrive for the plunger that moves when you push the release button. That looks like it would make the drivepiece weaker. Not as much cross section metal.
I think the newer professional stuff might have that drilling a bit smaller than on the old Craftsman roundhead. All have a little metal drilled out at right angle for the ball and spring (or pushrod for the quickrelease) but I don't think that drilling goes all the way to the base on the non quick release.
It just comes to my mind that I don't think there is such a thing as a quick release on a breaker bar!
all the older QR stuff i have seen do not have the hole all the way through. only the newer stuff from my experience. i know usa made craftsman qr do not have the hole through, but the imports do.
edit - just took a look at roughly 15 QR ratchets from -v- to brand new, and only two had the hole, one was a taiwan craftsman polish, and a menards brand china.
i find that the pawl gear teeth mech goes long before the square drive shears, at least from my experience, and others ratchets i have seen broken
