That's good to hear for you, but I'm not just making this up. I have the XPS 13 9310 which mostly comes with the AX500 chip for wifi and bluetooth.
- For about half a year it had NO support in Ubuntu (non-existent drivers)
- Then it finally got drivers, but it was extremely unstable. After an automatic update from ubuntu, the wifi no longer worked and it took several weeks for it to be fixed.
- The bluetooth VERY often won't turn on after a reboot, requiring me to reboot about 5 times before it finally works.
- Same for wifi, even on the latest drivers it often can't find any networks.
- Some networks can't be found by the linux drivers. No problems at all under windows, with the same laptop.
- Crashes or freezes of the whole OS as a result of these drivers.
There's probably a ton more issues that I'm forgetting...
Oh and make sure you configure the nvme to AHCI in the bios. The intel raid stuff is trash and causes major battery / suspend issues in my experience.

On my 9343 bluetooth did not work initially, and on the 9370 the fingerprint reader is not available (no driver available), but apart from that linux is just working - and I'm not particular fond of spending time on setting things up.
Much more of an issue is that the xps, as every non apple computer does not support s3 sleep anymore. So just closing the lid and putting it in a bag can lead to overheating and battery drain.
Honestly I don't get, why we can't have decent power management unless you buy a mac.
