Spring trunk prop or gas strut?

Which of the these two options put the least amount of strain on the hinges on an early barracuda (66 to be exact)?
My driver's side hinge is a bit worn. As hard as it is to find good hinges I'm trying to preserve it as long as I can. I know the spring is constantly pushing on the the lid. Do the gas struts do the same? I know on some vehicles it kind of cams over and pulls down instead of push up.
