My Jeep came with rock sliders. I never intended to do challenging off roading so I thought about swapping them for a step. However they have saved my Jeep a few times off road so I will now keep them.
If you are not doing challening off roading, then steps are better.
In a tight spot I drive in forwards. If it is extra tight my wife will guide me. If I reverse in than I cannot open the tailgate because a wall will be in the way!
I drive forwards into my garage. Firstly its the exhaust and secondly, I can open the tailgate.
