Just that really. I have 2 young boys, one still in nappies. The other is almost 4 and goes sitting down. I don't see any reason to change this anytime soon, as I feel it's easier for him to not cover himself in wee. His father thinks he should go standing up. He can't reach to see standing up without a step and gets it on his clothes every time he's tried. We have a step at home but obviously won't elsewhere.
