the g600 is really uncomfortable IMO. the buttons are in a really flat layout that makes someof them awkward to hit.
the new naga 2014 curve is really comfortable to press the buttons. pictures of the mouse make it look really funky but it feels good in your hand. I've owned most any logitech, razer, madkatz, and various other mouse brands at some point and I'm seriously in love with the naga 2014. the mechanical switches are also a really nice touch.
and seriously. many people laugh off devices like this:

but it will completely change the way you play pretty much any game. getting used to a thumbpad over WSAD takes some time, but once you do you can't really go back. replacing a three finger function (wsad) with one finger (thumb) and then opening up those 3 fingers plus your pinky finger to easily hit 20 keys is no joke.
