Coming from a Cadillac sport wagon with a tight sport ride (which I thoroughly enjoyed) I find the QL quite comfortable. Much better than I thought it would be. I have the HA and the lack of body roll was as a great surprise too. I guess what I'm saying is it is more sporty than I thought it would be and I like that.
However, to slightly improve the handling of my '15 Limited, with the QL, I installed an SRT rear sway bar. It didn't turn it into a "corner carver", but it did help.....as I'm sure different tires would too, Nokian WRGs are rather "winter oriented".
I've rented the Limited w/o QL and found it has more body lean than my '15 HA 4x4 with QL. My Infiniti FX37 handled better than the GC, but had a much harsher ride. Since I don't hot rod around anymore, I prefer the more comfortable ride with enhanced handling of the air suspension. Big plus is the entry/exit mode that lessens my wife's moaning about climbing in and out. When I add the lowering links, she just might stop complaining altogether. I hope! To be honest, it's easier for me, too. I definitely wouldn't buy another GC without the QL. An added benefit is OR2 setting when South Florida gets torrential rains and deep standing water. Plus, with El Niño and global warming, we may soon have snow and the Polar Vortex down here.
I got the Off Road Adventure II with the air suspension on my Limited. During normal (not off-road & lifted), the truck rides great. The system compensates with leveling and firmness when I have a full load of people, 8 bags of concrete or pulling my ATV on a 5 x 8 trailer. When I go off-road and the suspension extends for more clearance, the suspension is noticeably firmer and doesn't let the truck bottom out. This suspension is the shit.:thumbsup:
Have posted my comments and experiences in another post on the QL suspension. Only recommendation I would strongly suggest is to see if you can get an super extended warranty on the QL suspension, say 5 + 2 years. And to make sure you have a good reputable Jeep service centre you can take your Jeep GC to.
I find that they ride similar. I've spent a good amount of time behind the wheel of a 2015 Limited w/factory tow. I like the adjustability of ride height and constant 4 wheel leveling. Mine does have a problem with skipping over expansion joints with the wheel slightly turned at speed. I'm not sure if that is a 20" wheel thing or a QL thing. I suspect wheels.
