I am also developer and I changed last year from Mac to Dell XPS 13". I would have stayed on Mac but the new keyboard felt strange, touchbar is... well I felt it is time to try something new. One surprising feature that I though I would never use is touch screen. I really like it and I thought it would be useless.

There are some things that I think could be better. I think Windows is a bit ugly, hardware does not feel polished like in Apple but it's not nowhere as bad as Dells used to be. The only thing I go back to Mac when I need to do iOS stuff and sometimes when i get something from designers in Sketch format but it is unlikely that I will return to MBP anytime soon.
