My favorite Windows is and probably always will be Windows 7, with XP close behind. However, as you said, if you want shit to work, you need Windows. Which is why I've dedicated my gaming rig to Windows 10 and call it an over glorified XBOX.
I'm a Linux guy now, some things may not work right all the time or sometimes not at all, but no OS is perfect. I enjoy the control Linux distributions provide.
Well I'm planning on running a few "virtual machines" with VMWare and have all of the older operating systems on the new machine. Windows 10 will be the main system and run the VMWare Workstation.
I've fiddled with Linux years ago (closer to decade ago) but a lot of things weren't supported back then. Things have changed and I'll definitely add a few Linux distros to the VMWare. I think Linux (the way its going) will be more mainstream in the near future. Atari's new comeback console will be running Linux, and if Atari repeats history they will be very influential to the public.
Get ready to be triggered in your safe space bitch!
