Air shocks have little to no rebound control compared to a normal shock, there is no real valving control in them, just a air bag for the compression that pushes back under pressure on the rebound. I had air shocks for many years on the back of a 78 ta, they functioned but had no real handling characteristics and the ride was very harsh even when only pumped up about half way. Switched to some cheap monroe sensatrack that had much better ride on crappy streets & way better handling on corners.
Many modern trucks & SUVs have air assist for ride height control, but theres a lot more going on in the valving & control of those systems than old school air shocks. Some models of Modern SUVs like 4runners have air bags in the rear for ride height or towing/load control, but they have standard shocks in the rear for normal ride & handling.
As with anything in this hobby, personal preference varies for each person, some say a certain muffler is too loud while others will think its quiet, same for shocks & springs, some say one brand/type has a smooth ride others will think its harsh. Lots of variables with each car/suspension set up too.
