Windows issues, customisation, privacy, less viruses, better for me as a dev, runs most of my apps I use anyways. The final straw was having to reinstall windows do to my networking, firewall and av being disabled, other people's support messages were too basic to fix the huge issue (wifi button on taskbar was gone, wifi/network settings crashed the app, firewall would not turn on: no fix other than reinstalling). Also, I run servers so it just made sense. Would love to hear other peoples reasons as well.
