I'm kinda a van halen fan but I've got two VH guitars. I've looked at tone zone , sreamin demon, Frankenstein, seymore custom custom for the bridgewhat sort of sound are you after? Both companies would make something you'd want.
I'm a true blue Dimarzio fan here, but both companies make great pickups. Depends on what you're after, as noted, they both make a pup for just about anything.
Steve's Special in the bridge and a PAF 36 in the neck is hard to beat for a solid do all setup in my experience.
the hottest i've gone is an Air Norton in the neck and Andy Timmons in the bridge. i didn't think i'd like a pickup as hot as the Timmons, but here we are. great articulation at high gain and actually cleans up well.

Dimarzios always seem more distorted to me than duncans. I don't quite get how a magnet and wire can sound that much different from one make to the next other than the number of windings and type of magnet but I've had much better luck with Duncans across the board. The only guitars I haven't used duncans were a few PRS pickups and some proprietary pickups but other than that I almost always swap out the factory pickups for duncans.

the PAF 36 is arguably the single greatest neck humbucker to be released from anyone in decades. That thing is infallible.
