They are pretty different pickups, as far as versatility I'd say the JB, only because the custom can be a little dark so it's not a perfect fit for every guitar where the JB is kind of "safe" for anything? The custom sounds amazing, by far the best pup Duncan has ever made I.M.H.O. but I only own Fender & G&L guitars? These kind of bolt guitars are inherently bright so the custom is right @ home in them, it gives them a beefy sound compared to, idk, a Fender Diamondback & also makes them extremely articulate @ the same time? If you were to put the custom in a S.G. it would just sound dull & muddy? If they are the only two pickups your considering & they're going to be installed into a L.P. I'd go with the JB, like I said it's safe? It's going to sound good in just about anything, I don't mean the custom wouldn't sound good in a L.P. but I think you'd be in a constant struggle to find a nice useable sound, you may even need to add a E.Q. to the mix in order to get what you want out of it where the JB is more plug & play, I think the Hybrid would be a nice choice for you & it kind of lives in between the two mentioned Humbuckers? Just my 2 cents though, good luck man!
