Well, the one is a bolt in unit,,, without boxing you still have a flexy frame... The other is nice, if you like air ride..... As far as handling, don't know. Never have driven anything with either set up in them. Being a MII guy, I probably can't be real objective about the others, anyhow!!! I don't need or want 7" of suspension travel, I can make a 3" travel coilover suspension handle like a slot car...... I guess they are both nice, if that's what you want....
