I think they're both pretty equivalent in terms of weight and materials, but I don't know that the Matrix version actually uses the same rocker profile as the gold seal. I know that Paramount has actually licensed the use of the gold seal and phantom profiles, it's why those versions cost more than the regular paramounts (which mimic the Pattern 99 rocker profile, but the pick design is slightly different).
I switched to the phantom profile paramounts a while back and they do seem to hold an edge longer - that's actually why I switched (going longer between sharpening), it had nothing to do with weight
I actually get "less" edge noise on mine unlike most people, but I went from a dovetailed blade (the phantom special, which was extremely noisy) to the paramounts, so I lost a bit of bite angle with the same ROH.. but that hasn't been a problem for me. I still get nice rip noises, they're just not as loud as my old blades.
Matrix Supreme run $385 (they are 440 stainless), Gold Seal profile Paramounts (best price I can find, which is from Kinzie's Closet) are going to be $449 for 440 stainless or $379 for the 420. You need coupons for those prices though (use P440 or P420).
Kinzie's Closet also has the best prices I've seen on Gold Seals at just $395.
