I only have experience with the Jazz neck and Humbucker from Hell in the neck. IME, Jazz neck sounds more like an earlier style PAF. Still PAF sounding, but more open and clear than say a more modern PAF equivalent. As for the Humbucker from Hell, it depends on what guitar you install it in, what amp you are using, and how you dial your amp in. Sometimes it can sound open and clear like an acoustic guitar, other times it can sounds somewhat stratty
IMO, get the Humbucker from Hell in the neck and PAF Pro in the bridge
