I can only comment on Cooma Gold and compare them to Shimano k03s resin pads. I believe they are brilliant and recommend these highly. When you brake them in properly the stopping power is way better than the k03s pads, sound wise they don’t squeal much only when wet and not warmed up yet. I have the combination with mt800 rotors. Modulation is maybe a bit less than with resin pads or atleast the lever range of modulation is smaller, but when you need stopping power they don’t disappoint at all. On high speed decents they are way more confidence inspiring than the stock Shimano ones.
