I don't rig either one of those ways
I rig my slider grubs on a weedless jighead (ballhead jig with fiber brush guard or Y guard).
Have not had any issues with less hookups, lost fish, or excessive hangups in cover. I also don't have any issues with Texas Rigging or Texposing causing tears in the body of those plastics, since the hook point is not placed back into the body of the grub.
For those that don't know :
Texas Rigging is running the hook through the head end of your plastics, then burying the whole hook point back into the middle of the body.
Texposing is running the hook through the body of the plastics, then running the hook point barely under the "skin" (outer surface) of the body of your plastics.
Both ways are used to make the bait "weedless" (less liable to snag than with an exposed hook).
