Clean, position insensitive (not that critical in 9mm), measures well, as reasonably priced as anything. I use it in 9mm,38spc, 357mag,45acp, 44mag. Works from low pressure plinking right up to near full pop mag stuff. Gets my vote almost always. Used to use WW231, its fine too, but Titegroup is happier at low volume/big case, so I switched.
