I've always found that Dell ships rock solid H/W, but does a piss poor job of systems integration. The best way to get "OSX Level" reliability that I've found is to clean-install Windows, or remove all their shitty Dell applications and tools. Their track-pad 'helper' tool is particularly quite terrible. Windows 10 too is its own beast. I disable all that update shit because like you I don't want any unplanned reboots. Its ridiculous that you have to do all this shit, but you will be rewarded in the end. I regularly get 40-50 days of up-time before manually rebooting for updates. YMMV !
