I've had very bad experiences with Dell's in the past so I'm staying away from them. My previous laptop was a Dell and it caused me more problems than all other laptops I've owned combined. And they are a tad... Overpriced imo. I mean an xps is around 25-30% more expensive than an equivalent zenbook for instance as a direct competitor. Currently I'm on a zenbook and it's been incredibly reliable. I intend to switch laptop soon and I'm between one of the newer zenbooks(yes, I'm aware of the bullcrap that is the screenpad, though apparently now it even works on linux out of the box) or an hp envy x360 which also apparently works out of the box.
I'm aware of System76 but I want to avoid buying a product that isn't that mainstream outside the US market. I can't recall even seeing one out in the wild anywhere. If something goes wrong with it, I'd need to ship it half way across the world to get it fixed. Not a very solid plan on my end.
I generally need a smaller form-factor laptop, otherwise I'd even consider something like cadnetwork because they too claim to have full linux support and even though they are a small manufacturer, in normal conditions(covid-19 aside), Cologne is a 3 hour, 40-50 euro flight away from me.
