This is only my opinion but, on our '01 RX300, I didn't like the GG Coefficient of Friction(CoF) pads. They never seemed to have the proper bite that I prefer in everyday-ness(such as OE pads or Akebono)compared to FF CoF pads. I too used Akebono ProACT on our RX. Loved'em!
However without realizing, I installed GG CoF pads(14 yrs later) before I sold the RX when with good intent, I just wanted to install new brake pads. The brand that I purchased just happened to be GG Cof. Recently, I installed new pads on my daughter's Mazda3 in my signature. These pads too were GG CoF and I'm not a keen on these either as compared to the FF CoF that I removed.
Even though the GG CoF brake pads are supposed to be the better pads, I am just not experiencing that benefit in everyday-ness from the initial bite nor when they're HOT!
Since you are considering using Raybestos, I have had very good success with their ProGrade and Service Grade Ceramic Pads. Low dusting, quiet, good bite and decent longevity.
However, this is just my experience and opinion. Good Luck!
