I have a Dimarzio set with a Gravity Storm bridge and a Fred in the neck of an SE CU24, and have been very happy with it. I believe the Dark Matter pickups are a Gravity Storm set with fancy covers. How it would compare to an EMG set, I can't say.
That being said, we've been chatting about things like string types and pickup adjustments in another thread, which often have a bigger effect than a pickup change, so be sure to check that out first!
