There is some debate as to whether the 8 outboard air bag suspension is superior to those with inboard air bags. They are just one of the factors determining ride and handling.
WB/OL (Wheelbase/Overall length) is another one. As is weight distribution.
To complicate matters, with rare exception, the chassis makers (like Freightliner, Spartan, Roadmaster/Monaco Corp) make a wide variety of chassis from entry level with small engines, simple suspension, to the high end. So, to a degree, it is like saying Ford Corp is better/worse than GM. They both make a wide variety of vehicles.
