That's because the XPS were built to run ubuntu. You can even buy one with it pre-installed.
I feel that it has nothing to do with manufacturer, though, just not good enough Linux support for laptops.
On the contrary, it's down to the model. As I type this on a fully-functional Thinkpad, I can assure you Linux is fine on laptops.
Windows has these rough edges, too, though. It's actually pretty shocking that here in 2024, PC manufacturers and OS vendors are still struggling with basics like sleep/wakeup. Last job I had with Windows laptops, everyone would walk around the office from meeting to meeting with their laptops propped open because nobody could be sure that their OS would actually wake up when they opened the lid. And when you closed it and went home for the day, would standby actually work or would it be on fire and out of battery the next morning? Somehow, only Apple has seemed to be able to solve this Herculean problem.
Bit of a stab in the dark here but I would assume ARM has at least something to do with this? Tablets, phones, etc. get standby a lot better than x86 systems seem to. My pre-M1 Macbook Pro does not handle standby well but my partner's M2 Macbook Air lasts for forever and handles sleep etc. well. The lower power consumption in "standby mode" on ARM seems like at least part of the picture for why Apple gets this so much better. I bet it's part of why Windows is trying to release their ARM variant and have been working on it for 10+ years
Intel mac on sonoma?
Just from an ACPI perspective, I'd expect the Linux variant to (at a minimum) be built with the Intel compiler and the Windows one with Microsoft's. It is likely that there are far more differences, though.
$1400 for a laptop with 1920x1080 at 60hz in 2024 is a joke. $200 more gets you a 3024x1964 @ 120hz, with an M3 processor and the ability to get warranty service walk-in anywhere around the world.
But I want a Linux laptop, not Windows or OSX. I also want a computer that obeys me, not some megacorp (not unrelated to the previous point.) I also want to not fight it all the time.
Can't comment about XPS, but I feel that it'll be the same.
Other than the pitiful 4 hour battery life, the laptop still runs fine, and mostly does what I need it to do for a permanently-docked daily driver.
(The external "carbon-like" skin texture just disintegrated on it after a few years, and the hinges got loose, but otherwise it is tip-top, still functional!)
