Exterior Door Handles

Hello All,
Was at Carlisle shopping for parts and was thinking about some door handles for my 1974 Plymouth Duster. All the major parts vendors carried them but there seem to be 2 different handles at 2 different price points. I have not had my door apart yet so I wasn't sure which type mechanism I needed. One type door handle had a metal ball tip (cheaper price) that connected to the inner workings to actuate the door mechanism and the other handle had a plastic type clip (TrimParts, authentic resto parts) that connected to inner inner workings to actuate the door mechanism. Can anyone offer any insight regarding the difference? Seems the metal ball tip would be stronger than the plastic tip.
