I've been using windows all my life and I've never seen anyone not say this about "their" version. Except ME. Fuck ME.
But seriously my dad refused to switch to Windows from DOS for the longest time. 95? The best. 98? Can't upgrade. Xp or die. 7 forever. 10 or bust. In 10 years it will be people clamoring over 11 and refusing to switch.
Windows 2000 was for enterprise, not home use. 8 was for mobile & touchscreens (at first) and that failed miserably yes, hence their 8.1 release. Just like ME they tried hopping on a bandwagon and it flopped. Two major flops in 23 years is not a bad record. But my point remains that when whatever new OS comes out, people look back at the last one with rose tinted glasses.
