Resonance no doubt...
simply because amongst your choices, it is the purest and bar none an ORIGINAL through and through by the master himself. The Octa Calendrier is another Journe original, but shares the space with the other Octa pieces like Chrono, RDM, Lune etc and IMHO just a tad lower on the Journe hiearchy than the Resonance.
The Lange Timezone, while exhibiting typical Lange precision and excellent finishing is but a variation of the icon for Lange which could arguably be the Lange 1. The PP 5960 houses two firsts by Patek, the annual calendar complication pioneered by them back in 1996 and it also has its first in-house chronograph movement. BUT putting them together IMHO dilutes the uniqueness of the complications and as such, dampens my enthusiasm for it, notwithstanding the nice gray dial and PT case.
Having said all that, the Resonance is the only one that can stand on its own merits, toe to toe with what the other guys can throw at it, hence is my choice amongst the ones you are choosing from.
