ADV is a conveniance and a BOV is a life saver.

As for breathing off a ADV???

Bov's work on flooded units and ADV's dont always.

The Golum is an Apex internals and breathes like an Apex and the ADV on my Classic breathed like an asmatic on a bad day.

To me there is no contest but others will no doubt disagree.
