Super Heavy is easier to control on landing because it's using 3 engines so has better directional control, and it can throttle those engines down into a sustained hover, which is what it does before being "caught" by the arms.
Surprising to see this work first time though - I don't recall them doing any hover and lateral movement tests, but I assume they must have done.
What's also wild is that the booster isn't being caught/supported by those giant grid fins, but rather by small lifting pins just below them, and seems to only have two of these (one on either side), so it also has to get it's rotational position right so those pins engage with (are supported by) the arms.
