GNOME or KDE?

[techlists at phpcoderusa.com]

In the past there has been some discussion about which is better GNOME 
or KDE?  I like Mint and I see it offers MATE (a fork of GNOME 2) or 
Cinnamon (a fork of GNOME 3).  It has been years and I think I selected 
Cinnamon for my desktop.

Does it matter?

I tried Ubuntu and I did not like it for my workstation.  However for 
servers I only want Ubuntu.

Thanks!!

PS I'm on a mission and might have dozens of questions.  Thank you in 
advance!!
