Dell XPS is an outstanding laptop, I've not found yet better laptop if you don't like macs
However, Dell is not going to be my next machine because:
- dev edition is hard to get (at least for me) and regular version does not work well with Linux (finger scanner requires to install OS patches, WiFi is dropping ocasionally , I had some crappy WiFi adapter installed in 2017/18, scaling is a big issue etc)
- mine XPS had a weirdly placed camera (bottom left corner)
- again, mine model did not have 4k display (comparing to retina I had back then)
- 13" is too small and 15" is too heavy, I would like something in the middle which might seem weird for you
- there is no finger scanner for dev edition (Yubico is here to help)
As you see those are very minor and subjective issues. Dell is a favourite machine of a friend of mine for years already, however I find Apple winning premium laptops battle in my eyes.
