The biggest thing is to go see them side by side in person. The H has larger bays. The H has staggered seating. Meaning the driver and passenger dont sit on the same plane. The H has a higher floor and therefore a lower ceiling height. Thats how it gets the larger bays. Depending on how tall you are, the ceiling height might be an issue. It was hard for me to get over. It felt really odd to me. However the upside is, to the best of my knowledge, there is no delamination issues on the H. Also IMO, the H feels more bus like. Good luck.
