Both products are very similar. The Firestone product comes with metal plates that would sit at the top and bottom of each bag. When the air pressure gets low, the metal plate can bounce, in the bottom bowl and makes a clinking sound, when you go over bumps. Sometimes it bothers me but does remind me to add a wee bit of air. I think the Airlifts may have plastic rings/stoppers and may not clink or rattle, at lower air pressure but would leave this answer, to folks that run the airlifts.
I have had my Firestones, for a couple of years, with no problems. Buy the one with the best cost, either one will work just fine.
Good luck
