What do you want out of a bump stop? They are all some of the best, just designed differently. SVC plus is it is adjustable but so is the RPG by using different size bump pads by removing one bolt instead of three on SVC. RPG is proven and think has been around the longest. Icon has a tension cross bar to tighten and when used with the RXT system can remove a spacer to gain more travel.
You can't go wrong with what you choose. Corey, Jeff/Jarrett and Dylan all are outstanding guys and will take care of you.
