it's pronounced 'cheppa' isn't it? See the animation below.
So Rzeppa is stronger than Bendix-Weiss, but what about Tracta? Anybody know which is strongest when you throw a Dana 60, or 70 with a U-Joint into the mix? G
Tracta & Bendix-Weiss joint:

From Wiki:
Alfred Hans Rzeppa (January 23, 1885 – January 1965) was an engineer working at Ford Motor Company who invented a version of constant-velocity joint in 1926. He proposed an improved design in 1936.
Rzeppa's design uses six balls and an inner and outer race to provide almost constant velocity torque transfer regardless of the joint angle. The joint works in a similar manner to a bevel gear with the balls bisecting the joint angle and functioning as the "teeth" to transmit torque.
