i use mostly MT3 ABS and PBT. the MT3 ABS has a rough texture on the scooped top, which i guess makes shine less obvious or maybe gives the impression of delayed onset of shine. that said, i rotate among different boards so maybe the ones i currently have don't have that much of shine yet
the few MT3 PBT sets i use have a rougher texture, with a kinda powdery feel on the fingertips which i understand some people don't like. im fine with using both
