I've had air bags on five of my trucks and really the brand isn't a issue, both Firestone and Air Lift offer great products that resemble each other very close. The real issues is the control, you need to decide what arrangement you are going to install to control the air bags. In my opinion, air bags would be worthless unless you installed an on-board air supply system. That is the true beauty of air bags, the control you have of them over the ride , terrain, and load. Also, air bags weather on your truck or on the big rigs will normally lose air. Yes it is important to have a sound supply and air line system, but the bags them selves are homogeneous and will over time lose air. Hence the importance of the on-board air supply system. They will make any truck ride better, but you need a sound system and for the ultimate in ride comfort, you will need to remove the over-load springs from the rear leaf springs. Good luck.
