Well you should tell that to Dell because I have coworkers with a range of their models that are constantly fighting with webcams, audio, bluetooth, wifi, and Nvidia driver updates.
If they're new models, the webcam issue is not Dell specific, but an Intel / ipu6 thing. It should be integrated into most systems by now though, even as an out of tree module. The rest should just work, especially on xps machines. Without specifying the models/issues, it's hard to take it as more than an anecdote.
They have a line they sell with linux pre installed. Those always work fine. It takes so e work to figure out which old ones on ebay were in that situation.
