I have an XPS 15. And while I liked that I could bring my own SSD and RAM, the build quality is nowhere near a Macbook Pro... like not even in the same galaxy. I had to have it serviced multiple times within the first few weeks. It had to be sent to Texas, and when it returned, one WiFi antenna wouldn't plug into the card, and the light on the front was permanently broken. I could have demanded Dell fix it - and I'd have been even more weeks without my main work laptop. So, by pure numbers/specs? Sure. By real world quality, no way would I favor Dell.
