G36K, M4, or AUG?

Hey guys, I was just playing Cross Fire when I realized that I was getting a bit bored of my G36K. I love it but I was thinking of trying something else. Should I stick to it, get the oh-so-common M4, or the AUG, which I just decided to include in this list because I kinda like it. And while I'm on the topic of guns, is it worth keeping a Desert Eagle with a rifle? It's totally sick but I'm starting to think it's kinda useless.

Anyway, all comments welcome.*
