I think the Tig's stock pads are pretty darned great for OEM brakes. But there's no doubt that I always want the best braking I can get (well, within the realm of my budget of $500).
I do agree with the others that the squealing may have developed from the overly-light braking technique. Same thing happens on my wife's car. I've had to take the pads and rotors off in the past and scuff them up with sandpaper to fix it.
Let's hope the Akebono material is less prone to that behavior and you won't see a return of the squealing in the future.
