Can confirm that my 2016-era XPS 15 model has the best trackpad I've used on a PC. I did have an issue where after a few years it became almost impossible to physically click (still important for click-and-drag operations), though after investigation it turned out that the dying battery was swelling up from below and interfering with the trackpad. So, full marks on the trackpad, but I hope they've ironed out their battery story.
