Bit of warning about KDE:
It is very customizable, but as a by product is also really easy to completely fuck up. The first time I used it (eons ago) I ended up removing the task bar and couldn't figure out how to bring it back or launch programs.
Just spend a bit of time reading up on it and you'll be fine though.
I want a clean, advanced, well designed desktop and Im okay with redoing my work flow
Use Gnome
Gnome is cool but can it be slightly more Windows?
Use Cosmic (PopOS)
I want lots of customization, advanced features, and a traditional windows desktop metaphor
Use KDE
I want Windows and don't really care about customization
Use Cinnamon
Dude the Windows 9x look was fucking dope
Use Mate
Im installing this on a potato
Use XFCE
