the only reviews/comments I ever pay attention to are from grassroots motorsports http://grassrootsmotorsports.com becuase they are all about autocrossing and more useful for anything suspension/braking than typical import magazines will ever be. Now if I were completely happy with metal masters I would say the hell with trying something else they work for me. So if you have them and are happy keep them. they aren't bad enough for me to change them before they wear out. I just noticed that most people use metal masters as upgrade pads yet most autocrossers use everything but. Autocross pads are ideal for spirited street driving and grassroots even classified metal masters as autocross pads. All I know is I want better and a big brake upgrade is out of the question since I plan on using 14" wheels to drag with (whenever that happens).
