In terms of aesthetic, I love Windows 7-era Aero glass design (and to a lesser extent, Vista), but I also love the classic Windows 9x/2000 look. If I had to choose between the two, I'd go with Aero simply because of the start menu search bar.
In both Windows 7 and Vista you could change the theme engine to Windows Classic, which gave you the Windows 9x/2000 look AND the start menu search bar.
Exactly. Windows 7 plus the windows 2000 "classic" option was pretty awesome.
Win10 LTSC with the right options and limiting search to local only is pretty good also though. Insanely snappy on even crap systems (with really any SSD)
