In terms of durability, Dell XPS is a consumer-grade product and should not be relied on for any serious work. The only real alternatives to Apple Macbook in terms of build quality, design and performance are ThinkPad X1 Carbon[1] and Dell Precision 5530[2], which is XPS business-grade counterpart.

Rather than say something snarky I would be interested to know what makes you say it is consumer-grade and should not be relied on for serious work. I use mine to run multiple businesses and my bank account suggests I do serious work.
Unlike its consumer counterpart, XPS, the Precision 5530 passed 14 tests for for MIL-SPEC durability, the standards that the U.S. Military equipment must pass for ruggedness. That means it can be operated in extremely hot and cold environments (as low as minus 20.2 degrees Fahrenheit to as high as 140 degrees), survive the shocks of drops and gusts of dusts, among other things."
