My wife and I currently use the Atomic SS1's, and have never had any issues (including deep >90fsw dives). It breathes as well as my B2 at depth, and both the purge and inflator buttons are easy to manipulate while breathing off it.
That having been said, I'll shortly be moving to a BP/W rig, and will be switching to an octo (I'll be doing more technical diving... Consistent dives >130 should be with a long hose separate octo IMHO).
One final point... I keep reading arguments here about divers ripping primaries out of their buddy's mouths. I'd be curious to know whom here it's happened to. I have friends/divers/instructors with thousands of logged dives, that have been involved in OOA scenarios, and none of them has ever had a primary intentionally ripped out of their mouth. But, perhaps that's just them...
