Any thoughts on this Brake disc & pad?

For what it's worth I had a full set of ATE discs and pads on a MK3 golf a couple of years back bought from ECP. They were absolutely atrocious. There is a world of difference between being an OEM and actually manufacturing OE quality parts.
 
Im running mintex front and back which are the same as standard but bit cheaper. Very little brake dust to compared to the OEM stuff
