PhoenixwuninFirst off,don't bo too bothered by your mousepad.It'll play both RTS games and FPS games equally well. Trust me,I use an exactmat (which has both control and speed sides) and enjoy shooting on both sides.
That said,what's important is what you want in your mouse.Main points of consideration,imo,include: -
CH :-
-Suited for both left and right handed users.Neon pipes give you a nice grip.
-Has 7 buttons,(5 are decently comfortable to reach,the other 2 will require some effort)
-Has onboard memory (really useful if you need to bring 5 diff settings along wherever you go)
-Has 3 different colors to choose frm (green really matches ur mat)
DA :-
-Has 3g infrared sensor (refer explanation below),which allows you to move your mouse at insane speeds
-Right handed shape with nice rubbery like top,really comfortable to hold.
-Side buttons (only 2,as opposed to CH's 4) are relatively easier to press
-Pulsating logo is cooler here

Explanation:-
About the sensor,it won't make a difference if you don't move your mouse at high speeds.The question is,do you move your mouse at speeds of 0.9m/s and above? I'm not talking about covering such a distance,I'm talking about speed (I know it's hard to quantify in real life,but u get the idea)
At such speeds,the Copperhead is known to buckle and you won't be able to track.The DA on the other hand can survive speeds of up to 4m/s (no gamer reaches this kinda speed,so ur DA will never buckle under speed)
So if you move ur mouse at high speeds (generally low sensitivity gamers) the sensor point is relavant and should be considered seriously.If not,you can take that particular point out from the consideration.
Edit :-
Or to make things easier for u,as sean392 (microsoft fanboi) has pointed out,u could try to get ur hands on both for testing,do some gaming and see which u prefer
