It always ends in personal taste. I don't like EMGs because I can'y feel any dynamics and I'm not a modern metal player.
Tonewise, I think they are too "polished" or "well behaved" to my tastes, with no sharp edges or what so ever if you know what I mean. The sound is too processed at the source, what can be good for some and bad for others. MAtter of taste.
I don't like compressed processed sounds, I like organic and vivid tones, where you can hear every nuance... and of course, you can hear your GUITAR, the whole thing, wood, hardware, string gauge.. Maybe people say EMgs are sterile because they process the tone in the very beggining and they put their own stuff over the sound, but it can also be good to make a bad guitar sound at least decent. Depends in what you want.
I can defenitely say that I will never use EMGs, actually, I can't use other pups after putting my hands on my first BK. The damn 500T /496R set in my Les Paul is Killing me, but I have no funds now to aford a BK set for her :(
