Does a w116 stop faster than a w123? I would think so. It's frightening how fast my car stops. Two weeks ago I had my car full of 3 other people and I locked the brakes up at 50 mph. Rear brakes locked also, something that seems just about impossible on American cars, but I've never stopped so fast in my life. It was like the seat belt was going to rip through my shoulder. I would assume the w126's are similar, but I think mine stops better than my mom's 420, and it has new pads, calipers, etc.
I've never driven a w123, I hope to some day to see what everyone raves about, but I hardly doubt they're as good as the w116 handling wise. Just my $.02.
Thanks
David
