I had a 2016 Dell Xps 15" and both me and my coworker with the same machine had terrible issues with the keyboard randomly writing letters twice in a row. Also the on-board nvidia graphics card, while nice, was also a big power hog and that system had bad battery life until I turned it off. After a couple of years, the battery puffed up and started pushing up on the trackpad until it was unusable. Really soured me on Dell's build quality, and I can't recommend them at all, even though I admire their support for linux drivers.
