Yeah. It's not so much the brand as the set up. I find Weinmann brakes stop as well as any other, in fact they are one of my favorites. If they are not working to your satisfaction, I'd try new brake pads first. After that, cables and housing. They should feel subjectively stronger than old DA if properly set up with good pads and cables etc. I hot rod my current modern gran compe version slightly by running Koolstop dura dual compound pads with a modern Tektro straddle hanger in the front. The hanger effectively shortens the hanger cable slightly, increasing the mechanical advantage a little bit.
