I'd say it depends on the sound you want. Everyone has their preferences- some like the duncan sound, some the dimarzio, some the emg. From what I've heard, blackouts are an improved emg but I haven't tried em yet. From personal experience I can tell you that the jb sounds great for leads but can be too flubby on the lows for rhythm. Emg 81 has sort of the opposite problem- very tight and clear but somewhat clinical and harsh in the highs. Right now I'm actually using a low output pup with fantastic results- duncan jazz bridge, a very very versatile and clear sounding pickup. Goes to show you can get good results in less conventional places as well.
