The SC2000 is effectively one player of the MC6000 (same jogs as 3000 and MC2000). Same buttons, jogwheels, indestructible quality. For scratching, I CAN imagine they are on the smallish side. But they have great grip are solid as a rock with no “give” whatsover and feel like you could press them like a Sumo wrestler.
Our scratching course tutor Steve is pretty enthusiastic about these jogs actually. So his seal of approval should be good enough for anybody.
But I haven’t done Traktor since I happily got rid of it over 2 1/2 years ago and have no interest in using the S8. So can’t help you there.
