I went from Matrix Legacy (Coronation Ace equivalent) to Matrix Supreme ( Gold Seal equivalent). It took me a while to adjust to the new rocker, and my Legacy blades were almost new (so no flattened rocker issues). I noticed that the Supreme rocker gave me more of a spring on jumps, especially waltz and toe loop and footwork seemed easier. Spins were the longest to get back as the spin rocker is very different from Legacy, but they felt faster right away.
In my case, though, I was dealing with a different brand of boots and a different blade all at the same time, so I am not sure how the blades alone would feel.
Overall- I like the blades now, but in the beginning I was worried if I had made a mistake. I sharpen them about the same as the Legacy, though the Supremes are supposed to have a more hardened edge.
