These are good questions, and I don't have good answers for them yet.
Justin and I are different people from Aquel and Johanna, our styles
are different.  We're a little younger.  In some ways, we're more
formal - I think courts may get a little more serious in terms of
spiffy and pageantry, but not stuffy (I can't imagine Justin doing
stuffy -- he was pouting awhile ago that if we became baron and
baroness he couldn't sit on the floor during court anymore!).  But at
the same time, there's room for more humor, and more acknowledgement
of people's achievements outside of the three baronial orders.
