I owned an Atomic Z2 and took it to 130 feet. It was an amazing regulator. No need to buy the B2.

Z3 shares the 2nd stage swivel, so that's not really a differentiator.From performance point of view, all atomics, from z2 to the titanium model, they are all exactly the same. From best bang for the buck stand point, z series is the choice.
What you are saying more for B2 is the titanium in 2nd stage, swivel on 2nd stage and swivel on 1st stage turret. Do you want those?
