2016 burb rear shock replacement advice

[6inarow]

Just trying to get guys 2cents on what to replace factory rear shocks with on wife’s 16 LT suburban. Just did leveling kit and noticed passengers rear was pretty shady along with passengers front outer tie rod. All this with 40k on it. Gotta love modern day engineering lolol. Anyways. Not sure if should go with bilstein 5100 series or like the top quality kYb brand off rock auto. Just don’t want a super stiff ride. Would be nice to have factory comfort ride maybe little stiffer since she has littler bigger tire. But she doesn’t haul anything but kids. Any info welcome thanks
