On a Dell XPS 15 9550: - Trackpad is awful and all the synaptics software and tweaks and configs I've tried can't make it work half as well as a MBP trackpad - graphics switching + sleep + power brick replugging + lid closing doesn't work ever - high power usage unless powertop --autotune is run, which breaks USB replugging and causes more havoc with sleep - mfg defect with the ribbon cable under the space bar causing the space bar to be almost unusable. Required a new keyboard and me tearing the whole thing apart to fix The screen is gorgeous though (thin bezels + 4K IGZO + capacitive touch which I don't need) and the hinge works well even when touching it. Build quality is OK but not micron-level perfect like MBPs (the seam where the metal meets the bottom shell is off by a tiny bit and catches my finger). The power brick is bigger than an MBP equivalent and they're not ubiquitous as the MagSafe2s now are. Having real USB ports is nice, since I hate the USB dongle I have Velcro'd to the USB-C power cable for the tbMBP. It also doesn't run Mac OS, which FWIW on the 2016 tbMBP fares about as well as the Dell with re-plugging two 4K DP USB alt-mode adapters -- I end up hard-powering the MBP >50% of the time since the internal displays and external displays won't show anything, even though the stupid touch bar lights up. I got the Dell used on eBay for about half of retail, which is about what I consider it to be worth, while I consider the 2015 rMBP to be worth ~$1600 and the 2016 tbMBP much less.
