That Entwhistle sounds very intriguing and at that price I should probably try it one of my guitars. The only other pickup I know about with a neodymium magnet is the q tuner pickups, which I'm also very curious about.
Also, in case anyone is curious, I now have guitars loaded with black hawks and lundgren m6 and another with an emg 81. Like everyone said the emg 81 is definitely the tightest pickup I've ever played (tighter than the aftermath), the black hawk is similarly tight to the miracle man, and the lundgren is considerably looser, but still sufficiently tight and very articulate. Also, the sinner is definitely not as tight as the aftermath (like I said earlier) or even the miracle man.
I guess the only other contenders are the EMTY blackouts and possibly something with neodymium magnets. I've only tried the regular blackouts and they were looser than the emg 81 and also darker, smoother, less aggressive, and IMO not as good.
