XFCE has features that you need 7+ Taskbar Tweaker for on Windows, like being able to middle-click a taskbar button to close it's window. Any feature XFCE didn't have such as "move a window to another monitor with a hotkey" were easy to script with xdotools or other similar utilities. With the recent release of XFCE (4.16 I think?) we got fractional scaling as well.
I also found it easier to add custom commands to Thunar's context menu than Windows Explorer. Thunar also has tabs and so does the XFCE terminal emulator.
Beyond that, I'm no longer constantly fighting with Windows Updates, Windows Firewall or Windows Defender or navigating the fragmented landscape of shells (PowerShell, Cmd, Git-Bash, Cygwin, etc.) just to get my job done.
When I setup a Linux workstation (Manjaro is my preferred distro), it stays the way I configured it without Microsoft constantly changing things out from under me - so I feel like I actually own the system.
