@rschwieb I think it's fine to be moved to MathEd SE, but I think the underlying question about which notation is better should be answered, because it's not just about pedagogy even though it was asked that way. What do you think?
@user21820 As I said, that seems to have "opinion based" written all over it, and I don't see the value. Questions that try to "settle which notation is better" are not usually very valuable. I don't think it's worth keeping around. Especially if it encourages more such questions.
