Max Loader Spring Support System vs Ride Rite Air Bags

Still doing research on which 5th wheel I'm going to buy. Short list is the Sundance 3600qb and Crusader 360bhs. My tv is a 2014 gmc 2500hd D/A. After reading multiple threads I had planned on adding the Firestone Ride Rite system. This morning I ran across the Max Loader Spring Support System and would like some feedback on positives and negatives of the above

I use air bags to level the truck out. I have added extra springs before but the air bags are all I really needed.

Air bags can be used to improve the ride as well as leveling the truck. Springs just give you more load bearing and does nothing to improve the ride quality.
