Which clutch is best, Borg and Beck or diaphragm?

AND NOW an annoying old story you guys may not believe. One day, long ago, some guy came into the parts store with what appeared to be a BB pressure plate and tossed it on the counter. IT JINGLED AND CLANKED??!!!

He says it's out of an AMC, I don't remember exactly which model, but here is how they work

THERE ARE NO SPRINGS AT ALL in the clutch pp assembly. The clutch linkage is REVERSED such that when you RELEASE the pedal (UP) to drive the car, A LARGE SPRING in the linkage actually PRESSED DOWN on the levers, and PUSHED THE PLATE against the disk. So the linkage action is bas-ackwards, and EVERY SECOND THAT THE CLUTCH IS ENGAGED, the linkage is STRESSING the T/O bearing and pushing DOWN on the levers to keep it engaged!!!!
