EBC or Brembo (4.6is)

[kevnmurphy]

Of all the links I have read, people say both are great. But is there much of a difference between the two besides $50?
Also, Since the 4.4i and the 4.6is have 12.8" rear rotors, does it matter which ones you order. EBC says the 4.6is rear rotors cost 251.10, while the 4.4i rear's cost 199.13.
I think for the Brembo's (rear), all models are listed at 205.95.

All prices according to http://www.autopartswarehouse.com/se...294967011+6854

Anyways, I would much appreciate some insight and I thank you in advance.
