GO Xposed!!! - you may never go back to "custom" - Actually, I am a bit of a "crack-flasher", but I always return to "Stock/Xposed" when I want something stable. My favorite Xposed module "Gravity Box" has most everything the custom ROMs have (status bar colors, navigation size, reboot menu, cursor keys, etc.) Add in a "quick settings" app and you can make 4.1.2 "look" about like Kit Kat. Does it hurt performance... Maybe, but I've found stock to usually run faster anyways.
(P.S. - I probably wouldn't have unlocked either if I would have found Xposed sooner)
