About landing the Super Heavy booster, Wiki[1] says:

Does anyone know the reason to choose "two mechanical arms", instead of landing like the Falcon 9? And has SpaceX announced any plans to test these arms? In my mind, it sounds more wild to try to "catch" the landing booster with arms, rather than land on a pan. Anyone else?
They were originally trying to land on pad, but they couldn't get legs light enough and strong enough not to bend while landing, there were also problems with maintaining structure around those legs. It was simpler to have two hardpoints and legs be more massive but on the ground.
