I've had a couple XPS laptops over the years, one XPS 13 and one XPS 15. Both have had issues with their trackpads getting wonky. They would just increasingly ignore inputs and react incorrectly to my finger. The XPS 15 (the 2-in-1 model) would also sometimes just not go to sleep and cook itself in my bag, and its keyboard has keys which just break over time under normal use, and that's not covered under warranty. You can't just replace the keyboard, you have to pay out of pocket to replace the whole top case of the laptop.
Your experience might differ, but I'm not getting a Dell again.
