Should I changed From SD Jazz Neck to 59?

I used to always have to have the Jazz in the neck position,but recently picked up a 59' and put in the neck position and never going back,for higher gain sounds/tones the 59' does it for me. Thats in Mahogany and Alder bodied guitars.

I use both, depending on the specific guitar and what I have in the bridge. The Jazz is a bit more articulate and a bit more full-range, so a great match if you need the neck with distortion. The '59 sounds very sweet though. They're both excellent pickups I like the Jazz as a nice match to higher gain pickups: the Custom in the bridge with Jazz in the neck is something I've used a lot. Still, my old Charvel still has the original '59 in the neck from when it was released and it sounds great too, but I match it with an old Screamin' Demon (not all that hot) in the bridge.
