I personally like DeWALT but they are both good. I currently have that same DeWALT set... evanbaker08 on a side not what year is that GTS? Actually getting rid of my Z06 for a built 98 GTS lol...
New CP 1/2" Impacts $250 bucks, cheap price. I paid more for IR that hits less. Emailed the guy and got his number, said he has 3 or them and he is fairly close ;) Might snag 1 up if my wife lets me.
