2133 CL11 RAM will have like CL7 when they run as 1600. So the GSkill one is much more better in quality. However you won't be about to notice much different tho they're RAMs use for insane OC.
I recommend this http://www.newegg.com/Product/Product.aspx?Item=N82E16820231441
Why? Cus you won't be noticing much different (says between 60 & 61 fps in gaming) between 1600 & 1333. Gaming rig = 1333 CL9 hands down. And I just love GSkill lol!
Or mayb a 16GB Corsair Vengeance 1333 CL9 kit is nice too.
