One thing that surprised me is a relatively high level of noise, even when the plane was cruising. Considering that this is a brand new plane and should supposedly have the latest/greatest materials, including the isolation, this was quite surprising to me.
An airplane built in 2017 is built using the exact same materials as a plane built in 1997. Newer airframes may have different/upgraded interior seating and overhead bins, but the wall paneling and insulation behind the paneling will be the same as the older airplanes.
