What soccer cleat is the best for me?

I've come down between two pairs of cleats that I am trying to decide between. The first pair is the Nike Mercurial Vapor VII (for $200), and the second pair is the Adidas F50 adizero TRX HG Cleats (also for $200). I wear a pair US 11.5 shoes and play in high school on a artificial turf field. I also play several different positions and tend to slip alot on my field when its wet. I usually kick with the front of my shoes so I want the front to be kind of hard(but also have good accuracy). I'm attracted to the Nikes because I like the colors more and that the material in front is harder than the Adidas. But I like the Adidas because they weigh almost 4 ounces less than the nikes(even though I don't think that would that much of make a difference to me). IN YOUR ANSWER PLEASE INCLUDE WHAT SHOE WOULD BE BEST FOR ME AND THE REASONS WHY IT WOULD BE THE BEST CHOICE. If there are any good shoes that you can think of that are under $200 then please tell me also.
