Out of the options - Windows 7.

I've actually only used it on a work computer. As far as home computers are concerned, my history is as follows:

• Windows 95: 1995-2000
  
• Windows 98: 2000-2005
  
• Windows XP: 2005-2010
  
• Windows Vista: 2009-2012 (A small overlap with XP here, because I got my Vista laptop a couple of months before the XP desktop blew)
  
• Windows 8: 2012-15 (Yeah, I upgraded from Windows Vista to Windows 8... that was painful >_< )
  
• Windows 10: 2015-present
  

Windows 10 is fine IMO, although the Start menu can be a pain sometimes. Windows 8 was a disaster. Windows Vista was decent by the time I started using it; however, by then, the damage to its reputation was done. Everything before that is basically just nostalgia at this point.
