Why does Jeep in particular have so much issue with quality assurance? The most memorable is the SUV rolling over in a simple test a couple years ago which have been fixed but it's quite worrying.
First off that test is somewhat of a joke for SUVs since it basically rewards car-ish handling which is at odds with the truck-ish performance that is demanded of larger SUVs
In terms of comparing two different vehicles...
If the $year base model $carA has a suspension system closer in performance to the sport model of $year $carB but for $year+1 they put a much softer suspension in the base model of $carA in response to customer feedback then the results go out the window. Alternatively, if the OE tires are particularly expensive then you can bet that most owners will replace them with cheaper one. Additionally, particular trims are often incredibly rare or almost always have a particular option added. So testing a $trim without $package will be of little meaning when the vast majority of $trim that make it to dealer lots will have $package. In either case the results go out the window because there's a handful of large variables that are uncontrolled for. It's little better than the comparisons you see in car commercials.
If you actually want to grill Jeep over something I suggest you read up on 90s XJ gas tank fires.
