Owning both sets, I'd take a JB/Jazz set any day. The Jazz neck is my favourite neck pickup of all time, and it balances really well with the JB (unlike the Juggernaut "callibrated" set). The middle position of the JB/Jazz is awesome for cleans and edge of breakup tones. The Juggs may be better at low tunings, but a JB with a boost has been the sound of many, many bands tuning low with great success. And if you need a more modern and tighter JB, the Pegasus will get you there.
