I do not know about the later models as I never drove one, but for 2013 my back-to-back testing experience is that yes, LX drives a LOT better on the road than the LC. It is not a slight difference. This is the biggest reason I ended up buying the LX not the LC. The AHC suspension is a piece of engineering that delivers. For me none are driving like a sedan or even a wagon (I own both). You know you are in a big truck, even with the LX. The magic of the LX is that it makes the ride surprisingly smooth and pleasant yet controlled on cornering braking and acceleration. You keep the road feel and that is important to me. These where both used trucks.
