I was going to write a big thing on this but I see Ben saved me the trouble and did it for me. :B
Every single point he made is on the money.
There is no "mine is the best braking setup."
There are many, many, many considerations when it comes to brakes. OEM is always a trade-off. BUT......so is aftermarket. They might be great at stopping but wear out in 5K. They might stop great when cold but when they get hot they don't stop very good. Life is always a trade-off and so are brakes. OEM spend billions of dollars in research to get the best trade-off setup. "Most" of the time they do a great job!
As far as slotted and drilled, listen to Ben. Why would you want to lose mass or take mass away from the rotor while towing? The answer is you don't. The reason aftermarket went to slotted and drilled is because of "off-gassing." Modern pads really don't have that problem so their is no reason to lose mass.
In short, you are going to have to really research aftermarket brake systems to get a better system. Even then, you will lose in some areas and win in others.
