When it comes to the how my distro looks, I’m very picky. This is why my desktop environment matters so much to me.
KDE is by far my favorite desktop. Why? One word. Customization. KDE Is definitely the most custom distribution with all the built in customization options. KDE is great for the person who loves customization but can compromise with using a GUI which looks a little old-ish (yes I think Plasma looks old-ish).
BEST FOR WINDOWS USERS
I think for a windows user Cinnamon will feel similar with the customization level being not too high but not too low. The big menu will also feel familiar.
BEST FOR MAC USERS
For a Mac user Pantheon desktop would be perfect. It’s very simple with a Mac like top-bar and a basic app launcher. At the bottom of the screen there is a Mac like dock. Pantheon is native to Elementary OS.
