This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

I personally prefer gnome, work in it is just faster with gnome shell and it's window management, but it's is very individual. You can install KDE next to the Gnome and test it without removing Gnome jet. – tikend Jul 1 '13 at 12:32
For installation check this – tikend Jul 1 '13 at 12:33
"And tell me which is better among KDE and GNOME" is a subjective question and possible flame war >:-) – Rinzwind Jul 1 '13 at 12:34
Yeah nobody can say what you'll prefer. Try it and see. – Oli Jul 1 '13 at 12:36

You can install KDE using this command

 sudo apt-get install kubuntu-desktop

To remove Gnome:

sudo apt-get --purge remove liborbit2


sudo apt-get remove gnome-desktop

Rather than installing the simple metapackage, consider installing the APT task. See Should I use tasksel, tasks in APT or install regular metapackages? – gertvdijk Jul 1 '13 at 12:56
