Raptor all the way. Its very smooth, almost vibeless, great on grinds, comes with 2 removable caps for different weight, feel, play, 2 extra sets of response pads (3 in total), has many colors to choose from and has a nice laser engraving on each side. It has a perfect size, not too big like a PGM, not too small like an extremely under-sized. It plays really well, just gotta love it.
Dv888 is not a bad choice either, but it doesn’t have the features Raptor has, and people claimed that the Raptor is smoother than it.
Go Raptor, you can’t go wrong.
