I have FerodoDS2500 + Motul RBF600 and stainless brake lines.
Iīve used them in track days (short track, no big braking zones, max from 130Km/h to 40Km/h or so) and no fadding at all.
They hae a bit more bite than stock, they bite OK in cold, and after two small brakes, you feel they brake more.
Im pretty happy for daily driving + ocassional trac (i havent tested them in a track with bigger braking zones).
About dust, I donīt see any relevant difference compared to stock ones, maybe a bit more, but as I have black alloys, they are always dusty for me
