Its all down to personal preferance plastic is lighter than the steel item so will affect how the car drives.
Plastic with savers will last fine without breakage but steel outdrives will last longer but increase the wear rate of the driveshaft pins. No matter which you use the diff will still need to be rebuilt just as often.
Also a lot of those who are using a steel diff are actually using the cr style with copper washers and not the d-ring outdrives
