That is total BS! You had better look again they are not alike and the Holland brake has been around a little bit longer.
The newest radial is the best brake I have used, and no ports on the bottom as another poster erronously claimed either.
I have found that the radial brake is much better than the older QD style.
It seems that the top 3 brakes for big guns right now are the Holland Radial, DE brake and the APS, take your pic.
