Ausar is better on defense especially helping off the weak side to get blocks and steals and has a more consistent shot. Amen is slightly more athletic (both amazing) but tends to force it which can cause more turnovers per assist. Amen prefers to attack the rim and dunk, but while Ausar does some of that, he likes to contort his body to split defenders and scoop it in. This reviewer gives a slight edge to Ausar. I've read that for most of their lives Ausar was considered the better player and would win most one on one. In the last year there has been a bit of a shift in perception from scouts favoring Amen.
