Less ballooning on the front wheels. A tiny amount of drivetrain wear. I personally use silicon earplugs, because it almost locks the diff, but doesn't fully lock it. It is a lot cheaper and has similar effects.
I love the dbxle 2.0. I would recommend trying to find a used one for around $800 (that is what I did). A lot of people buy this car and use it less than 10 times and sell on FB marketplace for $800ish
