If it's between those 2, the only difference I see is the Corsair Vengeance is about $60 less money for a 2 x 8GB kit. (not sure what you're going for).
You didn't specify a speed, but in most gaming cases, it doesn't matter too much. Usually 1866MHz is a good balance between speed and cost. If you're going for 16GB, I'd get this kit: http://www.newegg.com/Product/Product.aspx?Item=N82E16820233536'
G.Skill Sniper is also a nice set: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231611&cm_re=G.skill_sniper_ddr3_1866-_-20-231-611-_-Product
