Win98se was considered damn good, compared to what had come before. Disruption for little benefit, at launch, though.
2K was only for businesses, bad driver support and lacking in some software support on account of using the NT kernel before hardware & software vendors were expecting home users to have it.
ME was a pointless refresh of 98. Buggier and with system menus subtly messed-with to no purpose. The first miss-step of the Vista/8 variety.
XP was good by SP3. Not so much at launch.
Vista, yeah, slow as hell while adding nothing.
7 was still slow as hell, but wasn't as ugly and our hardware had gotten better so it was less-noticeable. Not much to recommend it aside from "XP's going out of support, and it's less-ugly than Vista".
8 was pointless and ugly, like Vista.
10 was another 7: de-uglified 8, but not much else going for it. Adware and shitware and spyware galore. This leaves 7 as the last "good" Windows.
11's 10 on steroids, so, two scoops of shit instead of one.
